"Crossing the rubble left by the Lawn Lake flash flood, the trail to Ypsilon Lake passes Chipmunk Lake, a surprisingly dramatic mirror reflecting Ypsilon Mountain. Ypsilon is the Greek letter corresponding to our letter Y. Very conspicuous Mount Ypsilon is named for the snow-fi lled gullies that form a Y across the huge bowl-shaped cirque cut by glaciers on the mountain’s east face. Ypsilon Lake takes its name from the mountain against which it rests. Switchbacks from the Lawn Lake Trailhead lift hikers through a ponderosa pine forest on the side of a steep slope laid down thousands of years ago by the icy conveyor belt of a glacier. The back-and-forth trail eases passage up and down this lateral moraine, but that is not the main virtue of switchbacks. They also eliminate erosion from hikers’ or horses’ feet by keeping this wear and tear on a less-steep slope, where it is less forceful and damaging than on a straight up-and-down path. Do not shortcut the switchbacks." Read more

"Spectacle Lakes lie at the edge of the Mummy Range, in Rocky Mountain National Park. Their mountain waters flow south through a narrow ravine, in multitiered horsetails amid mossy rocks and greenery, and spill into a shimmering, brown pool at “Ypsilon Falls.” The hike to “Ypsilon Falls” begins on Lawn Lake Trail, and follows the ridge above Horseshoe Park and Horseshoe Falls. At about a mile the trail meets up with Roaring River, and follows it for about half a mile before reaching the junction with Ypsilon Lake Trail." Read more
