I found a photo of the old beach at Windy Lake Provincial Park. I believe this photo was taken around 1985. The table that I was sitting on when this photo was captured is located remarkably close to where the more recent photo was taken in this trip report. A comparison of the photos reveals that the garbage bins no longer line the beach.
And here is a photo of the hill (the volcano-like hill in the distance) where the fire tower is located across Windy Lake (Cascaden tower). This photo was taken south of the hill from a helicopter on our way out to a grid. I was working as a summer student for Falconbridge Exploration (Mining) and was gathering rock samples in the area. This photo was taken in 1990.
