BRIEF DESCRIPTION
The central and northern areas of Mare Imbrium have no large craters, but a telescope pointed in the area shown along the northern edge of the chart at lunar sunrise or sunset will reveal the long pointed shadows of isolated peaks. In the past such shadows cast by a low Sun helped to convey the false impression that the lunar mountains are very high, steep and jagged.  Refer to your Antonin Rukl lunar atlas chart, page 49.
