Although the last leg home, this proved to be the most challenging of all. When we woke up, Edmonton City Centre had scattered clouds at 2,500 feet above ground level and broken clouds at 6,000 feet. West of the Rockies (Prince George, Wiliams Lake and Kamloops) it was clear. There was a front coming in from the Pacific that was expected to reach Vancouver in a day or two. It was clear we should try to get home today if we could.
Although Edmonton is almost due north of Calgary, it is much further away from the Rockies (just under 300 kilometres), because the Rockies run north west at about 45 degrees. One advantage of this is that there are fewer mountain ranges to cross. Once through the Yellowhead Pass near Jasper, we turn almost due south, following the river valleys, all the way to Kamloops.
Ernie took off just after 9.00 am and we headed east. We had gone about 50 kilometres when the clouds became broken and lower, down at times to 1,500 above the ground. Ernie decided to climb above the low cloud, as we knew the Rockies were clear. However, the lower layer was thicker than we anticipated, and above the lower layer was another strata of cloud at about 10,000 feet. As Ernie climbed ever higher to get above the lower level of cloud, it became clear that the two levels of cloud were coming closer together and the lower level was thickening.
It was too dangerous to continue, so Ernie did a 180 degree turn, then tried to find a hole in the clouds to begin our descent. He found one somewhere over Wabamum Lake, but when we eventually came out, the cloud was now down to 1,000 feet above ground in places. There are two power stations on Wabamum Lake with smokestacks at 500 feet, and all along the Yellowhead Trail, which was our route back, there were equally tall wireless towers. There were scattered rain showers and poor visibility and we scudded back to Edmonton City Centre airport, keeping over the Yellowhead Highway as much as possible and as high as possible to avoid the towers. We were relieved to find Edmonton much clearer.

We parked the plane again, and headed out for a coffee and a snack.
Edmonton to Kamloops
We got back to the airport and called flight services again for a weather report. The cloud west of Edmonton was thinning, and the satellite picture still showed the Rockies along the Yellowhead to be reasonably clear, with high, scattered clouds. Kamloops was clear, so once again, Ernie took off and headed west. The first 45 minutes or so were somewhat similar to our aborted trip, with low clouds and poor visibility. The further west we went though, the better the conditions and after an hour Ernie was able to climb through the clouds and at around 10,500 feet we were clear, with broken cloud below us. There was though a strong headwind.

In another 45 minutes we had passed Hinton and were starting through the Rockies through Jasper Lake. By now, we were heading due south.

At the town of Jasper, we made a sharp right turn (west) through the Yellowhead Pass to Valemont, where we again turned south. The Fraser River starts in the Yellowhead Pass, then flows north and west from Valemont, before turning south again at Prince George.

Although before we started from Boundary Bay, I was worried that the return through the Rockies would be the most difficult part of the whole trip, this did not turn out to be so. The weather was clear, and after a flight of approximately four hours from Edmonton, Ernie landed safely in Kamloops. But the most difficult part of the whole trip was to come.

After re-fuelling I called flight services for an update on the weather. It was a rather unusual report. First, there was thick smoke in parts of the Fraser Canyon due to two forest fires, one near Lilloet, and one at Terrace Mountain, north of Kelowna. 34 miles north west of Hope, there was a restricted area up to 7,000 feet, where firefighting aircraft were operating. Hope was clear, but between Chilliwack and Langley, low marine cloud had been hanging about all day, with ceilings as low as 1,500 feet. It was expected to clear by the time we got there, but then it had been expected to clear earlier in the day. Pitt Meadows was clear, with broken cloud at 4,500 feet.
By the time I took off, it was almost 5.00 pm Pacific (having gained an hour from Alberta) We decided to stay high and I climbed to 7,500 feet, heading west to Ashcroft along the Thompson River, then to Lytton, where the Thompson and the Fraser joined together. The weather was reasonably good, with some haze, but otherwise clear.

However, when we entered the Fraser Canyon at Lytton, we immediately came into thick smoke, with visibility suddently down to less than five miles. Ernie urged me to climb, and we had to get to 10,500 to get over the smoke. Fortunately, at 10,500 feet, we were well clear of the tops of the mountains, and could rely on instruments for direction.

Smoke thickening
As we passed down the Fraser Canyon, there were several small fires burning.

The combination of a sun low on the horizon and the smoke created interesting light.

Looking west, 50 kilometres north of Hope
Although most of the smoke had faded, visibility was not good, and so we had to lose height as we approached Hope. About 15 kilometres north of Hope, we looked right and saw over the mountains to the west of Hope what I first thought was snow, but must have been thick cloud. This must be the marine cloud that the weather forecast mentioned.

Thick cloud over the mountains west of Hope
The Fraser River takes a very sharp right turn at Hope through a narrow valley. As I approached over the city at about 2,500 feet, it became extremely bumpy. I hit a bad air pocket and dropped suddenly about 300 feet. I had to slow the plane down. Hope has a long grass landing strip, and as we turned right, we heard on the radio that someone was landing there. However, as we turned the corner, we were faced with what looked like a wall of white mist.
The cloud was rolling off the top of the mountain on the right side of the valley, but the sun was shining through on the left hand side just enough for us to be able to see the highway and the left hand side of the river. The valley here is less than two kilometres wide with mountains going up steeply to over 6000 feet on either side. We had to decide whether to continue or land at Hope. We decided to continue along the river at 1,500 feet while we could see at least five miles ahead.
Gradually, the valley widened, and about 15 kilometres along the river from Harrison Lake we had an amazing view.

We still had to fly low along the river, but as we neared Mission we could see the cloud beginning to clear ahead.

By the time we reached Pitt Meadows, the low cloud had completely lifted – we were home, safe and sound, after travelling over 12,000 kilometres, through one of the worse summers for weather across Canada.
