GPRA Ski Trail Map

Located on the southern flank of Government Peak, within the community of Fishhook and near the towns of Palmer and Wasilla, GPRA is a 1420 acre (2.22 square miles) parcel of Mat-Su Borough-owned land within the State of Alaska’s Hatcher Pass Management Area. GPRA is bounded on the west, east, and north by undeveloped public land. Private residential land lies south of GPRA. Long-term Mat-Su Borough plans for GPRA include amphitheaters, additional parking, a Frisbee golf course, a biathlon facility; and continued development of mountain bike trails, cross country ski trails, multi use trails, hiking trails, and equestrian trails. The map above shows only the part of GPRA with developed cross-country ski and singletrack (bike) trails. The Castle Mt. Fault is an interesting geological feature that cuts through GPRA. Similar to the San Andreas or Denali Faults, it is thought capable of large earthquakes. Over time, the north (mountain) side of the fault has risen a mile or more. Cliffs of broken and twisted rocks are exposed nearby in a roadside landslide where the Little Su River cuts a canyon through the fault trace.
