In an ongoing effort to protect habitat of an endangered frog species, Angeles National Forest officials have continued the closure of the Williamson Rock area until Dec. 31, 2013.

“This ongoing closure limits access to about 1,000 acres north of Angeles Crest Highway near Eagles Roost, and has been in place since December 2005,” said Angeles National Forest Officials.

The new Forest Service order for another year was effective Tuesday (Jan. 1).
