If you look closely, there are boulders on the edge of the crater, possibly ejected when the crater formed, and trails of pits that seem to move away from the crater. The exact cause of these pits is not currently known; they have been hypothesized to be ejecta from the impact, fractures created due to tidal stresses associated with Mars, or even craters formed from debris ejected from Mars itself in a large impact. The large crater is named Stickney after Chloe Angeline Stickney Hall, wife of the discover of Phobos Asaph Hall. Angeline Stickney was herself educated and an instructor, as well as a 19th century supporter of votes for women and the abolition of slavery in the United States. When she married she gave up her career, but continued to work in astronomy and offer support to her husband somewhat. Many couples of scientists at the time worked together but only had credit go to the man in the relationship, but in this case she requested comparable pay to continue doing astronomical calculations and stopped assisting after Asaph Hall refused her request. -JBB Image credit: Nasa/JPL/Malin Space Science Systems https://photojournal.jpl.nasa.gov/catalog/PIA01333 Reference: https://web.archive.org/web/20120826235010/http://maia.usno.navy.mil/women_history/hall.html
