FOR TUCSON & SE ARIZONA AREA:
Weekly hikes remain on hold due to high temperatures and humidity. Hikes were discontinued in early June due to triple digit heat and increased humidity plus the Bighorn wildfire which impacted the nearby Santa Catalina Mtns in the Coronado Nat’l Forest. Catalina State Park is scheduled to reopen Aug 2nd on a restricted basis after being closed for two months due to the impact of the 120,000 acre Bighorn wildfire. 25-30% of the park was burned and the latest threat is from flash flooding due to monsoon runoff from the mountains which will flow thru the park in several washes. Runoff from the burn scar is totally black due to fire debris.
