Your maps isn't showing up. You may need to adjust the permissions on it. Are you thinking of a route like this?
I'm planning on doing such a loop in early April this year with fingers crossed the weather treats me well. I've done the Sulfur Creek portion and know all about Fruita and been through Cohab and Grand Wash, but have yet to make it into Spring Canyon or up and over Frying Pan.
@Joey just posted a
report of his trip down Sulfur and looping back up through Sulfur.
Summer could be pretty hot, and I don't know how reliable the springs would be along Spring Canyon later in the year. On the other hand, you'd probably have some decent shade for many stretches through Spring Canyon and hiking up the water in Sulfur would probably keep you cool. Still, pushing a pace to do such a loop in 2 days in the summer, that'll take a lot of water to be safe.
