Explore the Moon - Alps Mountains

Background

The Alps Mountains (Montes Alpes) can be found on the northern edge of Mare Imbrium (Sea of Rains).  It is a mountain range that is approximately 50km wide and stretches for more than 250km.  The tallest peaks of the Alps reach nearly 2.5km and cast long shadows on the lunar surface.

Comments

The Alps (Montes Alpes) seem to get narrower in the southeastern region after the Alpine Valley bisects it.  This region seemed to have tall mountains as I counted 9 very spiky shadows of peaks.  The range stretched all the way from Plato in the north to Cassini further to the southeast.  There is a slight gap between the Alps and the Caucasus.  I did not notice very many small craters throughout the range except on the western lowlands as it transitioned to Mare Imbrium.

Location

To help you locate this object a map has been provided from the Royal Astronomical Society of Canada's Observer's Handbook.  It is object B, highlighted below.
