It is located at the head of remote Echo Canyon at approximately 40.61167°N, -115.44667°W, and at an elevation of 9830 ft. It has an area of approximately 29 acre, and a depth of up to 155 ft, making it both the largest and deepest lake in the Ruby Mountains. It is the major source of Echo Creek, which after exiting the mountains merges with other streams to form the South Fork of the Humboldt River.
