We have an area called Margaret Falls Canyon in a provincial park about an hour
away from us, so I'm going to try go get in there for a hike within the next
couple of weeks.
In the summer when it's 90 to 100+ degrees F, you walk into the canyon and the
temperature drops by a good 10 - 15 degrees. The closer you get to the falls,
the more the temperature drop.
I'll be taking pictures when I do the walk and post them on here.
