Description
Description: Elger
(IAU Directions) CARDANUS.--A fine regular ring-plain, about 32 miles in diameter, near the limb N. of Olbers. Its bright walls, rising about 4,000 feet above the light grey floor, are clearly terraced, and exhibit, especially on the S.W., several spurs and buttresses. There is a fine valley on the outer E. slope, a large bright crater on the Mare just beyond its foot, and a conspicuous mountain in the same position farther north. I have not succeeded in seeing the faint central hill nor the crater N. of it shown by Schmidt, but there is a brilliant white circular spot on the floor at the inner foot of the N.W. wall which he does not show.

Additional Information
- Depth data from Kurt Fisher database
- Westfall, 2000: 3.44 km
- Viscardy, 1985: 2.3 km
- Cherrington, 1969: 2.01 km
- Westfall's estimate of the depth is confirmed by measurements of the length of the shadows in LO-IV-169H, which give results of 3200-3600 m (the shorter shadows reaching barely to the floor). The central peak is about 680 m tall. - Jim Mosher
