Well I had no clue there was rock climbing at the McDowell Mountain Preserve.
This area is known as Sven Slab and hosts a bunch of routes; Primarily 5.6 - 5.11c. All are granite face sport routes except for some other areas which are strictly trad climbiing - Tom's Thumb (see pic).
This area is essentially on the north side of the Preserve and can be acessed through the Troon North residential neighborhood in North Scottsdale. Approximatley 115th Street and Alameda Road.
A campfire must be extinguished by drowning it with water, stirring with a shovel, and repeating that process until the campfire is cold to the touch. A campfire is still a danger if it has any trace of heat, and must not be left or abandoned. Wildfires can begin by abandoned campfires that rebuild heat on windy days and then blowing embers ignite surrounding grasses and brush.
