Figure caption: Cupid Spring. Small group of terracettes formed along break in slope of runoff area. Algae that grow in the runoff area of this spring impart a reddish-brown color. White travertine is freshly deposited; grayish areas are older travertine deposits from springs that are no longer active. No index card. Published as Figure 10 in U.S. Geological Survey. Bulletin 1444. 1978.
