I didn't do a trip report, mostly because I wasn't at the computer much last winter, so I really didn't post at all.
There are a couple of different hut systems here in Colorado as well as some independant ones. The most well known are the 10th Mountain Division huts which are mostly located in the high mountains south of Summit County and Vail and north of Leadville. Getting to the huts typically requires a skin up of anywhere from 1 mile to 7 miles and could include easy cross country type terrian, or more typically some advance steeper sections. Most of the huts are located just about treeline, which is typically 10-11,000 feet. They typically have a big common room downstairs and one or several common sleeping rooms upstairs. There is a woodstove for heat, propane cooktops and sometimes a wood stove with a baking oven for cooking. Water is obtained by melting snow and there are usually solar powered lights. No running water, flush toilets or showers. Most have outhouses, a couple indoors, but most requiring a little snowy hike, which can be dang cold in the middle of the night!
Most huts will hold 15 or so people (more or less), and it is possible to rent just one space rather than the whole hut, although on all of the trips I've been on we've gotten a group of people together and rented the whole hut so that we can have the place to ourselves. The huts are very popular and tend to fill up fast, in fact the 10th mountain huts hold a lottery in April to book trips for the next winter.
A typical hut trip for me would be 2-3 nights. Depending on how far in the hut is, the first day would just involve the ski in. The next full days we would ski around the hut, either going up higher, or if conditions were bad, maybe just sticking close to the hut. The last day we clean up and ski out. We cook communual breakfasts and dinners (we assign meal teams), and drink lots of wine and play lots of cards. It's really cool to be the only people for miles around and the night sky with no light pollution that high up is spectacular.
