NASA's Naming Convention for Studied Spots on Mars.

NASA gives names to every boulder, pebble, and rock surface they study on Mars to help the team keep track of what they're finding each day. Official names have been approved by the International Astronomical Union, while unofficial nicknames are based on terrestrial locations. The Curiosity and Perseverance missions stick to nicknames based on terrestrial locations, with the latest quadrant named after Roraima, the northernmost state of Brazil, and for Mount Roraima. Perseverance is exploring the Rocky Mountain quadrant and recently drilled into rocks at a location bearing the nickname of Rocky Mountain National Park's "Powell Peak."
