Appennines Mtn Range - Apollo 15 landing site (click image to enlarge)

The Appennines mountain range, by far the most magnificent range on the visible surface, with 3000 peaks, and extending in an almost continuous curve of more than 400 miles in length.

Some peaks rise more than 15,000 feet, The square-shaped mass Mount Wolf, near the southern end of the chain, include peaks standing 18,000 above the plain.

The last two peaks are perhaps most famous for forming the valley where the Apollo 15 was the ninth manned mission in the Apollo program and the fourth mission to land on the Moon. It was the first of what were termed "J missions", long duration stays on the Moon with a greater focus on science than had been possible on previous missions. This landing was considered one of the most scientifically successful missions of the Apollo program and started the last three J-Series missions that included the lunar rover and 3-day stays
