Trail 1: Twin Lakes - Lake Mary Loop (Tamarack Cross Country Ski Center) - 5.5 miles
This was a fairly tame introductory snowshoeing hike, with about 30% semi-packed and the rest fresh powder. The trail we chose traverses some preset loops around the Lake Mary area of Mammoth Lakes, starting by Twin Lakes, passing north of Lake Mary, and getting views of Horseshoe Lake, heading south around all the lakes, and then back to the start. On the return trip, we split away from the trail for an exploration of the Panorama Dome, which we were surprised to find had only one or two sets of prints at that time. Coming back down required some navigation of backcountry, as the only trails up were from the south, in the opposite direction of where we planned to go.
Trail 2: Obsidian Dome (June Lake area) - 6 miles
This was a short drive north along 395 from Mammoth, and the main trail itself was fairly tame. The semi-groomed path runs straight to the dome, and then loops around it in one big circle. Overall, the scenery was pleasant and the deer were abundant on this portion of the trail. However, not satisfied with the level of ruggedness to our snowshoeing adventures, we decided to cross country up some hills toward the top of the dome (or a mini-dome, it was hard to tell in the white wilderness). The terrain was fairly steep, and we were able to truly test our kick stepping as we zigzagged our way up the side of the hill. The view from the top was great, and we even were able to glissade down a few sections and save some time back, although we were more jealous of the cross country skier that was there sometime earlier in the morning.
Trail 3: Shady Rest Park Loops (Mammoth Lakes Town area) ~3.5 miles
Desiring a little more mileage, we took this stroll on what seemed to be a combination golf course and park during the summer season. It was extremely easy and mostly just gave us a chance to get some exercise in the form of speed-snowshoeing in a big loop. Recommended as a warm up.
