Excerpt:

Two teenage boys escaped injury Thursday night when they fell through thin ice on Indian Lake just off Rt. 80 in Denville, police said.

“We just heard them screaming for help,” said Fred Greenberg, who lives on the edge of the lake, closest to where the two young men fell in.

Greenberg called 911 but as police arrived, they found the 17-year-old and 18-year-old had managed to climb out of the hole and skate to shore.

They were checked out at a nearby hospital for hypothermia, and then released when they were found to be fine.
