Pluto Articles: HAVE STELLAR OCCULTATIONS PROBED CHARON'S CHASMATA?

A recent article on Charon with a different perspective. The Chasmata, BTW, are the clefts cleaving the plutoward hemisphere in two:

This image shows part of the feature informally named Serenity Chasma, part of a vast equatorial belt of chasms on Charon. This system of faults and fractures runs at least 1,100 miles (about 1,800 kilometers) long and, in places, there are chasms 4.5 miles (7.5 kilometers) deep. By comparison, the Grand Canyon is 277 miles (446 kilometers) long and just over a mile (1.6 kilometers) deep.
