Lake Viviane
Lake Viviane, elevation 6800', is the lowest lake of the Lower Enchantments. It's a 1500' elevation gain from down at Snow Lake to this spot. Quite a trudge, but once you get up here, trust me, your energy will be renewed. There's an awesome little beach here right by the outlet which makes a great rest stop.
One of the major attractions of the Enchantments is the yellow larch trees in the fall. Larches are one of the few (the only?) species of deciduous conifers. This means they are like pine trees in that they have needles, but the needles actually turn color and drop every year. Things start changing in late September, but October is probably the best time to see the turned larches.
Like many of the lakes up here, I find it hard to capture the entire scene with a single photo because of how high the surrounding peaks shoot up into the sky. The Temple and Prusik Peak surround the lake on the north side. The trail continues south, across the outlet. It can be difficult to find at times, so just follow the cairns. It you're interested in a short side trip, Temple Lake is to the north from here, just right over the hill.
