An unusual stand of ancient ponderosa pine forest growing out of the sand is the outstanding feature of the Lost Forest Research Natural Area, which is located in the northeast portion of the area. A remnant of a forest that existed in a cooler and wetter age, these pines survive on half the typical annual precipitation for this tree species due to unique soil and hydrologic properties of the area. The nearest forest is 40 miles to the northwest, yet the pines continue to reproduce and thrive in this environment.

Motorized vehicles are allowed in the Lost Forest on routes posted “open”. No cross country use is allowed. Camping is permissible in designated sites only. Camping areas are primitive. There are no facilities, water, or restrooms in the area.
