Lunar Pits project

User JFincannon posted this in the Chat thread and I think it warrants its own project thread:

Anyone up to cave hunting?  I was directed yesterday to the paper "Distribution, formation mechanisms, and significance of lunar pits" in Icarus which had a list of the crater locations.  Here is a summary of these locations (sorry for the poor formatting):
Crater, Latitude (deg), Longitude (deg), Number of pits>5m wide

King,6.5,119.8,51
Tycho,-43.3,348.8,66
Copernicus,9.6,339.9,43
Lalande,-4.4,351.4,19
Stevinus,-32.5,54.1,16
Aristarchus,23.7,312.5,13
Crookesc,-10.4,194.9,11
Jackson,22,196.7,7
Das,-26.6,223.2,6
Aristillus,33.9,1.2,4
Kepler,8.1,322,4
Klute W,38,216.7,4
Adams B,-31.4,65.7,20
Dollond E,-10.3,15.7,2
* Messier A,-2,46.9,2
Near Wood S,43.9,235.7,2
Ohmc,18.3,246.2,2
Proclus,16.1,46.9,2
Stefan L,44.4,251.9,2
Guthnick,-47.8,266,1
Harriot,33.3,114.4,1
* Hayn,64.6,83.9,1
Milichius A,9.3,327.9,1
Near Virtanen,15.8,177.3,1
Palitzsch B,-26.3,68.2,1
Picard,14.6,54.7,1
Rutherfurd,-61.1,347.8,1
Sharonov,12.4,173.1,1
* Wiener F,41.2,150,1

If you want to join in, take one of the references above and find the pit and post an image in this thread.

Some contenders for the second pit in Messier A (Extreme left and right - and the small dark pit at the bottom, which is the same as the one on the right in the previous image).
Approx coordinates: -2, 46.9
NAC M126622485RC

This is the closest I can come to a pit in Hayn crater at the coordinates 64.6/83.9:

Will keep looking.

Dollond E,-10.3,15.7,2  Two pits.  Funny looking one.  Mickey's ears?

M1103467217RC, roughly at -10.27401, 15.70181. 

Kind of annoying that they did not give the precise coordinates, but rather the center of the crater.

Not easy to find in huge craters.  Fortunately Dolland is only 6 km diameter.

I recall reading an article (on Io9 I think) which cited research which stated there are over 190 known pits on the moon.
