One positive side effect of the drought in the SW is that the San Juans have about 65% of average (and decreasing) right now. This should be the best opportunity in several years for a early to mid June hike without a lot of drama.
Northern Colorado is a different story. Snowfall is considerably above normal from around Salida northward.
A hiker caused a large, destructive fire in Colorado a couple of years back when he went to get water from a creek and left his Alchy stove unattended, which blew over. The USFS in Colorado has been on alert for non-compliant stoves since then.
Do the right thing and use an approved stove. Send your Alchy one to Salida and start using it again north of there.
