  • The 32th item in C. A. Wood's list of Concentric Craters (1978) is the one south-southeast of J. Herschel F. It is noticeable on the Hi-Res scan of Lunar Orbiter 4's photograph LOIV-152-h1. In this part of Mare Frigoris, near J. Herschel F (between La Condamine and J. Herschel), a curious field of twisted arc-shapes is noticeable. Among these twisted arc-shapes, several concentric craters (and possible concentric craters) have been detected. Research: Danny Caes

Description: Elger

(IAU Directions) J.F.W. HERSCHEL.--A vast enclosed plain, about 90 miles across, bounded on the E. by a mountain range, which here defines the W. side of the Mare Frigoris, on the S. by massive mountains, and on the other sides by a lofty but much broken wall, intersected by many passes. Within is a large ring-plain, nearly central, and a large number of little craters and crater-pits. The floor is traversed longitudinally by many low ridges, lying very close together, which at sunrise resemble fine grooves or scratches of irregular width and depth.

  • Depth data from Kurt Fisher database
    • Westfall, 2000: 0.9 km
    • Cherrington, 1969: 1.7 km
  • Over 8500 m of the eastern wall were measured (using the shadows cast and LTVT) and the depth of the crater varied from slightly less than 1600 m to less than 400 m (Boint, "Profiles Of Features In The J. Herschel Crater, Fontenelle Crater, and La Condamine Crater Area", Selenology Today, Vol. 9. 1-12.)- fatastronomer
  • Large pyroclastic deposit (area = 666 km^2) on SE part of floor near rim, unusual in containing olivine in volcanic ash. Gaddis, L. (1999) Lunar Pyroclastic Volcanism Project.
  • South-southeast of J. Herschel F is a concentric crater.
  • The outside western rim of J. Herschel F rises between 650 m and 720 m above the surrounding mare. (Boint, "Profiles Of Features In The J. Herschel Crater, Fontenelle Crater, and La Condamine Crater Area", Selenology Today, Vol. 9. 1-12.). - fatastronomer
  • One could ask questions about the origin of the crackled (or fractured) region east of J.Herschel C on the floor of J.Herschel itself (slightly westward of the eastern section of J.Herschel's rim). Is this fractured region related to the phenomenon of the Floor Fractured Craters (FFC) which was once investigated by Peter H. Schultz in 1976? - DannyCaes Sep 5, 2014
