It took the Microsoft Flight Simulator (MSFS 2020) for me to discover this landing strip on Grosse-Île. Even the Canada Flight Supplement (CFS) from Nav Canada does not mention it.

Decades ago, Canadian authorities used this island in the middle of the St. Lawrence River as a quarantine site for immigrants arriving in Canada. Many Irish people, among others, made an obligatory stop on this strip of land before being allowed to continue their journey to Canada.

At one time, a section of the island was reserved for Canadian and American researchers for their top secret research on Anthrax.The most amazing thing about reading the article is realizing that the entire production of this bacteriological weapon (439 liters) was mixed with formaldehyde and put in barrels that were dumped somewhere in the St. Lawrence River when it was decided that it would no longer be useful, as the Second World War took a turn in favor of the Allies. It seems to me that formaldehyde does not prevent barrels from rusting, but hey… back to the point.

Today, tourists can visit Grosse Île and the Irish Memorial National Historic Site during the summer months using the services of Croisières Lachance, located in Berthier-sur-Mer.

Where is Grosse-Île located? In the province of Quebec, a little east of Quebec City. It is one of the many islands that you can fly over once you have left Île d’Orléans behind. Below, a screenshot from Google Maps.

The satellite image below clearly shows that this is not an invention. Microsoft designates this runway as CYMN Montmagny: a mistake that one can easily live with, since by giving an official code to this Grosse-Île runway, the pilot can use it as a navigation point in his GPS.

So, let’s use a small Cessna in US Coast Guard colors to make a virtual flight from Quebec City airport (CYQB) to Grosse-Île (CYMN). It was a bit chilly on this February day in Quebec City, so I decided to transport us to July for this flight, adding a few cumuliform clouds in the process.

This short flight will allow us to fly over Île d’Orléans, Île Madame (owned by Laurent Beaudoin, former major shareholder of Bombardier), Île au Ruau https://www.journaldequebec.com/2019/11/12/lile-au-ruau-vendue-395m (purchased in 2019 by the rich boss of the Gildan empire) to finally arrive at Grosse-Île.

The picture below shows the aircraft on a right base for the Grosse-Île runway. I do not know the official dimensions of this dirt airstrip, but it can easily accept a Cessna aircraft such as ours.

A final screenshot shows the Cessna taxiing down the runway after landing. As you can see, the runway can accommodate much larger aircraft. If you want to make a real flight to this island, find out beforehand about the condition of the runway and the restrictions surrounding its use by visiting pilots.

Photography in Europe: Gruyères and the Moléson in Switzerland

The city of Gruyères is located in the Prealps, in the Friburg County in Switzerland. It is a very charming small medieval town where cars are forbidden (the white van shown in the picture above is only used for morning delivery). In the city, one can visit the Gruyères Castle (Château de Gruyères), the H.R.Giger Museum (creator of the “Alien” in the movie Alien), the Tibet Museum, a cheese factory and boutiques. There are also some restaurants.

In the picture above, shot with a Canon 5D MKII, it is possible to see the Moléson in the background, a mountain that rises only 512 metres above the surrounding terrain but is still at more than 2000 meters above sea level. It is a tourist attraction that should not be neglected since it is very well equipped for all types of visitors, with a funicular and cable car. The visitors also have access to very interesting walking paths, for all ages and experiences.

When you use a cable car and do not see where it is leading due to the presence of clouds, you have to trust human engineering. But we are in Switzerland, so it should be all right!

The Moléson summit offers superb views. The small cumuliform clouds visible in the morning around the mountain progressively lift up due to daytime heating and eventually become beautiful cumulus clouds that add life to any pictures.

Once on top of the Moléson, it is possible to use a modern metal stairway to gain even more height and access a platform allowing an unobstructed panoramic view. The picture above was taken with a Canon EF 16-35mm f2.8L II USM wide-angle zoom lens equipped with a polarizing filter.

When ready to go down the mountain, the visitor has two choices: travel with the cable car and funicular he used when coming up, or slowly walk along an easily accessible path through beautiful green landscapes. The more experienced trekkers might decide to walk along the crests of surrounding mountains. We chose to walk on paths covered with flowers.

Back to Gruyères, a visit of the Château de Gruyères and both museums is a must, as well as a tour of the cheese factory. You might want to spend some time in the boutiques too and try the local restaurants. It is also the moment to take a few pictures…

The old architecture of the buildings in Gruyères as well as the neighbouring countryside allow for very interesting photographic compositions. A well-known photography technique consists in using an opening in a building and using it as a second frame (a frame within a frame). I made sure that the background was clear enough to improve the visual effect. An aperture around 16 allowed for an appropriate depth-of-field.

The picture above shows a spiraling staircase inside the Château de Gruyères. I can barely imagine what the results would have been if I had had access to the new Canon 11-24mm wide-angle lens. But nonetheless, the Canon EF 16-35mm f2.8L II USM zoom lens did a good job.

The beauty of the full frame sensor mounted on the Canon 5D MKII DSLR is that a wide-angle shot taken at a 16mm focal will stay at 16mm while with a smaller sensor, like the APS-C, the photographer is facing a conversion factor of 1.5 or 1.6X, which transforms the 16-35mm wide-angle into a 24-52mm, in the best of cases. The APS-C sensor is interesting when used with a telephoto lens but a bit less when comes the time to take wide-angle shots.

The picture below presents the Château de Gruyères seen from a neighbouring field.

As the sun was setting down, I tried a shot from inside the castle. It was interesting to see the two little boys standing up alongside the wall and admiring the sunset. At the same time, it was possible to see the Moléson in the distance, its summit hidden in the clouds.

Due to the strong light contrasts, it was necessary to use a Hi-Tech ND graduated filter installed on my Canon 16-35mm wide-angle zoom lens. The Digital SLR Photography magazine, in one of its recent editions, made a comparison between ND grad filters and indicated that the Hi-Tech filter had a slight magenta coloration instead of a neutral grey. I think it is easily visible in the picture below. The photo could have been corrected with Photoshop but I thought of keeping it as it was since the scenery looked somewhat unreal already.

Once the sun was below the horizon, the more subtle colours gave a totally new look to the countryside. On the picture below, it is possible to see on the right a small path that a visitor can take to head down to the nearby village.

All the sceneries are not that easy to capture and it is sometimes necessary to use HDR photography to extend the dynamic range and take care of extreme light contrasts. The photo below needed five different exposures that were subsequently processed with the Photomatix image editing software. Useless to say, it was necessary to use the mirror lock-up function, a tripod and a remote control release.

Here is, as the final picture, an idea of what is waiting for you at the H.R. Giger Museum. If there is a strange but very interesting museum, it is this one.

Photography and weather

Some cloud families

Cumuliform clouds add energy to any photo. Even photos in black and white benefit from them largely, whether it is for a normal or an HDR photo.

The stratiform clouds add to the tranquillity and the stability of a photo.

Clouds including a stratiform and cumuliform components (stratocumulus) produce an effect that is more energizing than the simple stratus, while avoiding the explosion of energy of the cumuliform clouds.

The cold front

The approach of a cold front enhances the possibility of interesting photos. If it is a fast moving cold front of moist and unstable air, the photos will probably be more spectacular, as some thunderstorms will be associated with the system. A dew point of more than 15 C indicates the presence of a lot of water vapor which can be transformed into precipitation, thus releasing a lot of energy. When these conditions are combined with a really strong contrast between the new air mass which approaches and the one which goes away, the produced meteorological phenomena will certainly be intense.

In the photos below, the meteorological system approaching the Quebec Jean-Lesage international airport also had to cross a small mountain range.

The morning fog

The morning fog offers many opportunities for interesting photos. You can choose an isolated tree and capture the combined effects of the morning sun and fog. Or you may choose a cluster of trees, for a completely different effect. Both photos below were taken in Domaine Cataraqui, Quebec City.

A morning fog resulting from a cold cloudless night will persist for hours if there is no wind. The cold morning air, motionless over a slightly hotter stretch of water, creates a fog that will finally disappear just before noon, when the atmosphere has been heated enough. If there had been an overcast sky during the night, chances are that the air over the water would have remained at a higher temperature, preventing the formation of fog.

The opportunities for more interesting photos arise when you witness the first holes in the fog layer.

We can take into account the season to estimate the speed of the diurnal reheating of the lower atmosphere. A morning fog will need more time to dissipate from late autumn to early spring: that leaves more time for the photographer to prepare. The forecasts can announce the disappearance of fog while it will not be the case if, over your sector, there is an invading layer of stratocumulus preventing the morning sun from reaching the ground.

To determine if the fog is going to dissipate as expected or will remain and possibly intensify, watch the difference between the temperature and the dew point on the hourly meteorological observations issued by weather stations near your place of residence. If the temperature and dew point spread increases, the fog is going to lift. If the difference between those two decreases, the fog is going to persist and possibly intensify.

 

The mist

The mist can be qualified as such when the visibility is superior to ½ mile, but do not exceed 6 miles for an observer on the ground. If the visibility is of ½ mile or less, it is called fog. This photo of the Bic National Park, near Rimouski, shows the interesting effect that the mist adds to a beautiful landscape.

Hot and unstable air in winter

When there is a warm and unstable air advection (about 0 degrees) while winter has already settled, there are good opportunities for photos. A moderately developed cumulus produces significant snow showers and this snow sticks on all the surrounding objects. All that snow would have begun to melt on contact of objects if the latter had had a temperature superior to zero degree. But, the winter being already settled, the snow persists. It gives enough time to capture some souvenirs.

The local effects

A photographer might benefit from learning about the meteorological local effects influencing the regions he intends to visit. The local effects are often simple to understand and they repeat themselves regularly, according to wind and season changes. The knowledge of these effects allows the photographer to be ready and position himself even before the phenomenon occurs. It limits the comments like: “If I had known that it would occur, I would have settled down here one hour earlier!

The local terrain as well as large size bodies of water produce predictable meteorological phenomenon that can be used by a well prepared photographer. It can consist of persistent fog, repetitive snowstorms over a small sector, strong winds, cumuliform clouds alongside the mountain summits, etc. By being positioned at the right place, at the right time, the desired photo can be realized.

A change in the wind direction

A change in the wind direction suddenly increases the opportunities of interesting photos. It might announce the approach of a cold front, a warm front, a sea or land breeze, etc. In the photo below, a bit of fresher air suddenly began crossing the St-Lawrence seaway at the end of the day, thanks to the approach of a weak cold front. The water was still relatively warm and the moisture which was present over the surface became visible due to the cool air supply. The conditions were now ideal for a short-term thin fog, as long as the wind speed would not increase. Just in time for a photo.

Familiarization with weather radars

It can be useful to get acquainted with weather radars which, for the needs of photography, remain simple to interpret. Multiple echoes of small dimension with a steep gradient of various colors indicate precipitation resulting from cumuliform clouds. The showers associated with these clouds are often moderated or strong and will be the result of approaching towering cumulus or cumulonimbus (thunderstorms). A towering cumulus presents a dark base and a white summit to the photographer. At sunset, their vertical development can be used to emphasize the last rays of light.

Large echo areas of similar colors of low intensity indicate a relatively stable air generally producing steady light rain or drizzle. This should be understood as a possibility of increased humidity limiting the visibility through mist or fog.

 

Hoar frost

Hoar frost is a short-term phenomenon. It is thus necessary to capture the scene before the sun melts everything. The photo below shows some small twigs on which hoar frost has settled. It was taken at the beginning of the seventies. Although the quality of the photo is not exceptional, the meteorological phenomenon is well demonstrated.

Forest fires

Wishing to make photos of western Canada during summer 2014, I came up against a season where hundreds of forest fires were raging. The smoke was covering some parts of Alberta and British Columbia. Some fires were important enough to require the closure of the sole highway connecting Lake Louise to Jasper. I thus decided to include the effects of those fires in the holiday souvenirs.

A visibility reduced in forest fire smoke allows a photographer to obtain, without special editing, sunsets with interesting colors.

The smoke also produces an effect similar as fog, but a fog which would be impossible to obtain at the end of a summer afternoon while the sun shines and there is a 38 degrees Celsius temperature.

At dusk, the residual smoke is visible near tree tops while the setting sun strikes the mountain side. The effect is of two horizontal lines of complementary colors, blue and orange.
