CommentsThis location is line of sight from Lake Travis Mansfield Dam launch dock. It is in the opposite northeastern corner of the lake. The colonies extend along the rock wall to the small marina that has private boat slips. Colonies were accumulated along the rocks and limestone shelves. The exposed cliffs revealed a series of exposed colonies that were possibly dead from drying.
