Los Angeles County Department of Public Health and U.S. Forestry Service officials have closed the Broken Blade, Twisted Arrow, and Pima Loops of the Table Mountain Campgrounds in the Angeles National Forest after tests confirmed that one ground squirrel trapped on July 16, 2013 during routine surveillance activities tested positive on July 23, 2013 for plague. The sites were officially closed at 1:00 p.m. today, and will be closed for at least 7 days. Campers at the site have been notified of the closure by Forest Service officials. The campgrounds and recreational areas are located near Wrightwood. In coordination with the Los Angeles County Department of Agriculture/Weights and Measures, the squirrel burrows in the area will be dusted for fleas. Further testing of squirrels will be done before the area is re-opened to the public.
