Residents asked if studies had been started on the impact of the trucks, machinery and actual mining on the environment of and near the proposed site. Concerns were raised about ruining a favorite recreation site that the city and many indiviuals have put much care and work into. Safety, noise and particulates in the air were also concerns. I did not hear one supportive comment from any attendee for the mining of the canyon. Mostly people were autraged and astounded that a conditional use permit was even being considered for Rock Canyon.
