B&W Photo Challenge: Avalanche Tunnel

_DSC0157

Cee, who loves hosting and participating in photo challenges, called for geometric shapes for her black & white challenge this week. I immediately thought of this “tunnel” built on the highway going west, beyond Kicking Horse Pass. This is a treacherous pass in the winter due to frequent avalanches, and thus they built these structures on the sides of the mountain to cover the highway. I assume that the snow continues to move down the roof and on down the mountain. I’m not sure I would want to be in this “tunnel” when thousands of pounds of snow was passing overhead. This is a major highway, so needless to say we didn’t stop in the tunnel so I could get a sharp photo – I had to settle for clicking on the go.

A little bit of mystery and wonder along the side of the road, at a stop on Highway 1 west of Lake Louise in Canada.

Kicking Horse Pass – Spiral Tunnels

_DSC0246

I am drawn in by trains, probably because my Polish grandfather worked at the rail yard, living a block away because he had to walk to work. I saw lots of trains when we visited – waiting for long trains to clear before we could cross the tracks to get to their house. The town where we lived in lower Michigan was a major rail hub with rails radiating out in all directions.

As we drove Highway 1 (Trans-Canada Highway) west from Lake Louise, we needed to pull in when we came to the spiral tunnel at Kicking Horse Pass. When I exited the truck, trees blocked my view but I could hear the rumble of trains below and the screeching of breaks. We had seen a spiral tunnel before so I knew what was there for my camera to capture but I had to get to the clearing. There it was…

This is one train, with the front of the train going to the left on the bottom, and the end of the train going into the tunnel. It is descending down the mountain.

pure engineering wonder.

Kicking Horse Pass is a high mountain pass (1627 m, 5339 ft) going across the Continental Divide in the Canadian Rockies, the Alberta and British Columbia border (Wikipedia). The Trans-Canada Highway and the railroad cross this pass, connecting the east coast with the west. Driving the Trans-Canada Highway through this pass is breathtaking with high mountains and steep grades. But this is about the trains.

British Columbia joined the Canada Confederation in 1871 on condition that a railway be built connecting British Columbia with the east coast. The biggest obstacle was the Rockie Mountains. Several passes were considered but the Kicking Horse Pass was chosen because it was the southern most, close to the US border, and the most direct link between east and west. It required the least amount of work and material, but it was also very challenging.

There was a lot of pressure from the government to get the railroad built so the engineers weren’t free to find gentle declines – instead the government temporarily allowed a 4.5 percent grade. The first train to go over the pass in 1884 lost control on the way down and crashed, killing three train workers. Because the danger was so high, side tracks were built for runaway trains which were the default, with the switch being turned for the train to continue down only when the switchman was sure the train was under control. This was a crazy dangerous train ride!

The solution for safer travel was the Spiral Tunnels designed by J.E. Schwitzer, one of the railway’s Assistant Chief Engineers, modeling them after a system used in Switzerland. The initial rail bed had been used for 25 years but were abandoned in 1909 when the Spiral Tunnels were completed. The Spiral Tunnels were a great improvement for the grade, this is still a challenging rail line because of rockfall, mudslides and avalanches that continue to be threats from nature.

The train we saw came from the west (upper right corner of this diagram). It had gone into the higher tunnel we couldn’t see (lower right of diagram) traveled 0.6 miles (991 m) through the tunnel and emerged 56 feet (17 m) lower. It crossed under Highway 1 and over the Kicking Horse River entering the Lower Spiral Tunnel in Mt. Ogden. It went 0.6 mile (891 m) and emerged at 3 on diagram (bottom of my photo) 50 ft. (15 m) lower.

Train Tunnel in B&W

I love black and white photos that other people take but find it… well, abhorrent to take the color out of my photos. This photo of the opening of a spiral train tunnel at Kicking Horse Pass and the Continental Divide in the Canadian Rockies told me to go black and white. And a red, high contrast filter made it perfect.

There is more story to this tunnel so stay tuned.

Along the Highway

Along the edge of Highway 93, going south in the Canadian Rockies from Jasper to Lake Louise, for miles and miles we saw large patches of “something.” Jim thought they were flowers but I knew they were seed heads. Know how, when you look at a ceiling fan a certain way, you can make the fan stop and see an individual blade for just a fraction of a second? As we were driving I could do this as they moved past my side window. I could see the feathery seeds waiting for the perfect moment to let loose.

I didn’t see any blooms and I don’t have my wildflower guide so maybe one of you out there can tell me what they are. For now I’m enjoying the photos I took – I think they are quite lovely. Something like dandelion seeds. I would also like to know where else they grow.
