  1. 122 craters in field. The largest crater, No. 1, is 26.5 m in diameter and 6 m deep. Other crater diameters in crater field are 19.2 m (No. 4), 11.4 m (No. 12), 11.2 m (No. 14), 7.0 m (No. 27), 6.8 m (No. 28), 5.2 m (No. 36), 4.9 m (No. 37), 2.2 m (No. 61) (Krinov, 1971). NOTE: summary for all craters including diameter, depth, number of meteorites recovered and their weight are provided in a table p. 329-343 (Krinov, 1966). Precise data for size distribution known for 158 craters and holes given on p. 223 (Krinov, 1963). In total there are 122 craters with diameters from 0.5 to 26.5 m and 78 holes with diameters less than 0.5 m (Krinov, 1963) (Krinov, 1966). Dimensions of largest crater (Aaloe et al., 1974).
