However, avoid the concept of pampered luxury . This is a Geology Field course and not a guided tour with all of the comforts of home. Pack all clothing and personnel items in one soft duffel bag. Your bedroll and tent are not counted as duffel bag items. Bring enough field socks and underwear for a week between laundry trips.
Rain can come at any time.
Cool weather can be anticipated in the New Mexico locations and in Gunnison. Two-Person tent if you have one. A good flashlight or headlamp - surprising where you need to go in the middle of the night while camping. Solar shower - a nice hot shower after a long day in the field is extremely refreshing. Towels, hand soap, shampoo, tooth paste, etc.
