Moon Places #7: Hadley Rille

Description:
Hadley Rille is a sinuous rille, a long, winding valley on the Moon's surface, stretching over 100 kilometers and reaching depths of 400 meters.

Formed by ancient lava channels where flowing molten rock eroded the surface, it later collapsed as the lava cooled and drained.

Located near the Apollo 15 landing site, the rille features steep walls and boulder-strewn floors, offering evidence of the Moon's volcanic past.

How I Got My Name:
Named after John Hadley, an 18th-century English mathematician and astronomer who invented the reflecting telescope, contributing to lunar observation tools.

Interesting Fact:
Apollo 15 astronauts David Scott and James Irwin drove the lunar rover along its edge in 1971; it's over 100 km long and 1.5 km wide. They collected samples showing layered lava flows, providing evidence of multiple volcanic episodes over billions of years.

Location:
Near 26.1° N, 3.6° E.
