Oblique view looking east towards Chaski Bay. The distance across the bottom of the image is about 2.6 kilometers (1.6 miles).
A major lake floor feature in this view is the extensive landslide
deposit that originated in the caldera wall at Chaski Bay. Characterized
by irregular topography and isolated blocks, the Chaski Bay slide
separates the southwest basin from the east basin. At the western
margin of the slide (A) is an area in which warm water vents
into the lake. This area is marked by bacterial mats that were
discovered by scientists aboard the Deep Rover. Remnants of the
failed caldera wall that fed the Chaski Bay slide can be seen
in the form of large down-dropped blocks up to 200 meters (656
feet) in length. Other landslide deposits are found west of Eagle
Point, in Danger Bay, and in the east basin.
