ИСТИНА

A few time ago Shevchenko et al. discovered of evidence of avalanching and of other downslope movement of material that is clearly visible on the inner walls of the crater Reiner. In general, freshly exposed lunar material is brighter than undisturbed materials nearby. The brightness of the avalanche scars is an indication of their freshness. The image shows numerous bright avalanche deposits on the steep crater walls, apparently originating at outcrop ledges near the top of the wall. The maturity index values of the different soil areas ranging from box 2 to box 4 correspond to exposure age from 6 to 0.5 million years. Similar features were discovered on the image of crater Daniell recently.
