The valley, which is only about a mile across and two miles long, is formed by a seasonal wash (Red Canyon) and contains thousands of mushroom shaped pinnacles or hoodoos ranging from a few feet high to 30 feet high that someone obviously thought resembled goblins. The formations have large orange/brown boulders of hard rock atop weaker sandy layers which have eroded more quickly, as a result of millions of years of the combined effects of wind and rain.
From I-70, exit onto Highway 24 and drive south for approximately 24 miles to the signed park turnoff, which is also the turnoff for Temple Mountain. From the Hwy 24 turnoff, follow the paved road for about 12 miles to park. Ample parking. Restrooms.
