Radial Dikes 
Spanish Peak dikes - from the top of West Spanish
Peak looking north
Radial dikes commonly radiate outward from a central igneous plug. A radial dike swarm is generally considered to be the roots of an eroded volcano. The body forces created within a symmetrical stratovolcano edifice set up the stress regime in which the radial dikes intrude outward from a central intrusive plug that feeds the overlying volcano. Radial dike swarms have been mapped in Colorado about four miles east of Ouray, 18 miles northwest of Gunnison, 2.5 miles north of Del Norte, 15 miles west of Walsenburg, and 20 miles southwest of Walsenburg.

Please visit the Silver Mountain and Summer Coon Volcano pages to further explore the geology of Colorado's radial dikes.
