Cooper Spur is on the northeast side of Mt. Hood. For a long time it was the standard route to the summit. You can climb from the Cloud Cap Inn directly to the summit. It is the most direct route but more dangerous and difficult than the south side route. I climbed it in early October before any snow fall. I went up past tie-in rock to about 8600'. You can see the crevasses in the Eliot Glacier.
