The Spur Cross Ranch Conservation Area in Cave Creek has some really fascinating petroglyphs placed there by the Hohokam that you can see during the Rock Art of Spur Cross Hike on July 14th, Aug. 26th, & Sept. 16th. The July & Aug. hike starts at 7 am. The Sept. hike begins at 8 am. An Interpretive Ranger or Park Docent will lead this moderate 2-hour hike. You should dress appropriately and bring water to drink. Dogs are not allowed during this hike. Registration is not required, but there is a $3 per person fee.
