We start out driving and hiking into the dunes at Great Sand Dune National Park. The following day we hiked into there South Colony Lakes Basin where we camped below Crestone Peak and Crestone Needle as well as Humbolt Peak. Here we saw Mule Deer and a Snowshoe Hare. On our hike up Humbolt Peak we saw many Marmots and Pika. We forgot our fuel cartridge for cooking and were very grateful to be given a spare from Jeremiah from The Colorado Climbing Company in Colorado Springs.
