The roughly 300-m-wide Barva crater lake is surrounded by dense forest.  The clear waters of the shallow lake are about 8 m deep, and a pH of 4-5 was measured in December 2002.  Near-surface black lapilli deposits were found that were more than a meter thick near the lake. Photo by Raul Mora, 2002 (University of Costa Rica).
