Helen Lake
 Helen Lake is located in Glacier National Park in the U. S. state of Montana. Helen Lake is at the head of the Belly River and is situated below Ahern Peak to the west and Ipasha Peak to the northwest. Numerous small streams feed the lake in addition to melt waters from the Ahern Glacier which descend 1680 feet (510 m) over Ahern Glacier Falls in one sheer drop to a talus slope below in route to the lake.
