Abstract

The Alpine Valley (Vallis Alpes) is a great fault that splits the Alps Mountains. It is about 80 miles long and up to 7 miles wide. It is plainly visible in my 2.4 inch refractor at first quarter. With my 6 inch refractor I can sometimes make out parts of a rill that runs down most of the center of the valley. Be sure that you show this exceptional fault to the guests at any public viewing. It is sure to become one of your favorite areas on our sister world.

Protagoras (13 miles) is a sharp crater north of the valley. It is a little over a mile deep.
