Pike's Peak, a summit of the Rocky mountains, in El Paso co., Colorado, about 75 m. S. of Denver; elevation more than 14,000 ft. above the sea. It is reached from Colorado Springs on the Denver and Rio Grande railroad. The distance to the summit from this point is 19 1/2 m.: the whole can be travelled on horseback. Two enormous gorges extend from the top almost to the base, one of them visible to the naked eye at the distance of 80 m. The summit is nearly level, embracing about 40 acres, and composed of angular slabs and blocks of coarse, disintegrating granite. It affords one of the grandest views on the North American continent, extending nearly 150 m. in all directions. In the higher parts of the gorges snow is perpetual. Pike's peak is named in honor of Gen. Zebulon M. Pike, who discovered it in 1806. The discovery of gold near its base having been reported in 1858, Pike's Peak became for a time the popular name of the Rocky mountain gold region within the present limits of Colorado, though remunerative diggings were not developed within many miles of the mountain.
