Frog Lake / Crab Creek / Marsh Loop Trails Professional Review and Guide
"By late spring, this area becomes very hot and dry, yet every valley bottom is covered with lush green vegetation and at least a small body of water —be it a creek, a lake, or a largish bog/mosquito hatchery. While the small waters are rich with aquatic life, the desert begins 1 or 2 feet above the waterline, with prickly pear cactus, sagebrush, cheatgrass, lots of dusty bare ground, and rattlesnakes.
In winter, bitter cold weather settles in, and a cold silence envelops the land—until the birds wake up. Then you’ll be blasted awake by the call of the 100,000 ducks and geese that stop in this refuge during the annual migration. Most notable of the migratory birds are the sandhill cranes that stop over in March each year."
