A botanical garden planted by the Friends of the Ironwood Forest. Interestingly the area around this pullout is a restoration area which was created because a man illegally built an airstrip here. http://www.aznps.com/documents/Scheruin ... _Final.pdf
“ In March 1981 Harlow Jones, a mining entrepreneur and small aircraft salesman, illegally bulldozed 18 acres of undisturbed desert bajada on the northwest side of the Watermans. The disturbance included a one-kilometer airstrip. Starting in 1982 Mr. Jones lived on-site with his family, until he was declared a trespasser by BLM in 1997 and forced to leave. BLM requested that Mr. Jones plant vegetation on the disturbed land. Mr. Jones responded by planting buffelgrass (Pennisetum ciliare). By 2005 the entire 18 acres as well as 10 acres of peripheral desert were heavily infested with buffelgrass.”
