Olcott

D=80 km
Center: 21°N, 118°E

Floor Area = 1479 km^2
Observed Density (@ 1km): 3400 ± 1500
Simone's Age: 2.4 ± 0.2 (+sec: 2.5)
Stoffler epoch: Eratosthenian
Fit Density (@ 1km): 3100 ± 200
PF fit: good


Age Calculation Notes: 
Fit is pretty good. Last bin falls a little below. Used Melosh gravity.

USGS geology: 
Eratosthenian

Wilhelms: 
Eratosthenian

Floor material: 
Deep crater, but small, eroded peak. Hummocky and smoother areas. No evidence of embayment at crater wall. Likely original.

Geology Observations: 
Ejecta blanket and secondary field visible. Rim looks slightly eroded. Small central peak that looks eroded. Collapse on south side of crater (excluded), may be caused by formation of a younger crater near rim. A few small secondary chains identified. All ~500 m. Formed near mare. Surrounded by filled craters.

SFD Observations: 
Slightly steep shape. Dominated by class 3. Classes have similar shape within error. Slope(Diff)=-4.0 ± 0.1
Secondaries diameter smaller than primaries, so shape not comparable.
