This animation is an excerpt from the "Colorado Geology: late Eocene to middle Miocene igneous history" video (in progress). This animation was developed to illustrate the morphology and evolution of the Spanish Peaks, southern Colorado.

0 to 15 seconds: The fly-around illustrates the general 3-D morphology of the Spanish Peaks.

15 to 32 seconds: This close-up view is near the base of the Peaks and shows a prominent ridge (light color) that is vertical dyke that emanates from the Peaks.

32 to 41 seconds: Aerial view showing several of these radial dykes.
41 to 44 seconds 3D aerial view of the Peaks and the radial dykes.
44 to 48 seconds: the surficial cover is removed to illustrate the interpreted distribution of the igneous bodies below the two Spanish Peaks; the mesh shows the surface topography.

48 to 57 seconds: The formation of the radial dykes is shown.

57 seconds to 1.04: 3D view of the radial dykes and the Peaks in the background.

Animation is by James Adson, Joseph Rogers, and Eric Lobato. A special thanks to Chuck Stern and Lang Farmer for their technical input.
