IWLOP #006 – Petavius
A lower Imbrium crater with a massive, complex central peak and floor uplift as indicated by rifts. This is an excellent example of a "floor fractured" crater.

R1: Petavius quite a large crater with a very large and irregularly shaped central peak.
R2: Rimae Petavius was very evident and easily identified. It went basically across the crater from the central peak (refer to sketch).
R3: Wrottesley appears to be NW to or on the outer part of Petavius's wall and has a faint central peak. It's not as terraced as Petavius. The shadow on its SE wall seems to extend outwards from the crater - perhaps from ejecta (?).
C1: I was very excited to see how easily Rimae Petavius could be seen. I followed it to the inner eastern rim and out the south wall.
C2: Noticed dark materials at 1 and 5 o'clock on the crater floor.
C3: Rimae Petavius continued southward until it met with the crater Hase (refer to sketch).
