You won’t find Grebe Lake on a postcard in the gift shop, but it was simple and pretty and a great base for hiking Observation Peak.
Originally, I planned to go only as far as Cascade Lake since my National Geographic® Trails Illustrated™ Topographic Map indicated that would be a 7.6 mile journey. Trail signs and my old friend “distance = rate x time”, however, put the round-trip distance at about five miles. I had no excuse for skipping the 875′ climb to Observation Peak and bringing the day to an even ten miles.

While not as impressive as the views from Mt. Washburn, the summit provided a different panoramic perspective on the valley. No bighorns up here, though some of the resident marmots were curious and/or concerned about my activities.
