Gross Reservoir is a large lake on the other side of Flagstaff Mountain. There is a hard-packed gravel road on it's eastern shore which is a great place to snap a few photos after the tough climb up Super Flag and long descent down. If you are unwilling to take you bike on gravel, however, you still get great views of the reservoir and the surrounding area at the junction on the pavement.
