VIDEO: Concerns Grow Over Large Crack Along Lake Whitney Cliff

A giant fracture in a limestone cliff overlooking Lake Whitney is threatening another luxury home, less than a year after a mansion was burned to the ground before it could collapse and fall into the North Texas lake below.

The U.S. Army Corps of Engineers says it is "very concerned with public safety" in light of the new crack. Chopper 5 flew over the long crack Tuesday that could soon put another luxury home in danger of crumbling into the lake.

The Corps of Engineers said Tuesday it will work to "keep things as safe as possible in the area until the danger has subsided." The group said that while the issue involves private property who are ultimately responsible for correcting the problem, they will help in any way they can.

In July 2014, fire crews burned down a luxury home teetering atop a crumbling 75-foot limestone cliff over Lake Whitney, rather than wait for it to tumble into the water.

Chunks of both the cliff and the 4,000-square-foot home fell into Lake Whitney for days.
