@ Calling all naturalists for a citizen science event in Castle Rocks State Park and City of Rocks National Reserve. We want to find as many flora and fauna species as possible to celebrate the first days of spring. We will be using iNaturalist to capture data for this event. Meet at the Castle Rocks/City of Rocks visitor center at 9am to get instructions on data collection and maps of the area. Vehicles without a State Parks Pass must pay the $7 motor vehicle entry fee upon entry to Castle Rocks State Park, however there is no fee in the City of Rocks National Reserve.
