Inspiration: Cascade Volcano Elevation Maps

Mt. Rainier

Mt. Shasta
I’d like to climb a mountain with my dad. He has climbed many of the peaks in the Cascade Range, including Shasta, Hood, and Rainier. I was talking about it with him the other day, and he suggested Mt. McLoughlin, in southern Oregon.
So I was looking around for information about it, and came across these neat elevation maps of the Cascade volcanoes, on the University of Wisconsin at Stevens Point website. The sharply contrasting colors indicating the different elevation intervals are really cool looking. I wonder how hard it would be do do a Cascade Range quilt?
