Two assembled orbital Hasselblad photographs of Rima Hadley are included in the book Full Moon by Michael Light and Andrew Chaikin (plate 34). These photographs are AS15-81-10892 and 10894. Research: - DannyCaes Jan 1, 2008
Lunar Orbiter 5's Frame 105 is one of its vertical close-ups of Rima Hadley and environs.
Rocks and boulders on Rima Hadley's floor and slopes are seen in AS15-84-11287. This 500 mm Hasselblad was also included in the book Full Moon (plate 73).

Depth data from Kurt Fisher database
- Viscardy, 1985: 0.4 km
The rille is a thermal anomaly feature due to exposure of fresh rocks on its walls - Moore et al, 1980
Length at least 135 km, ave width ~ 1.2 and ave depth ~370 m (from Greeley (1971) quoted in F. Leverington, 2008).
See Apollo 15 site for other features visited by those astronauts.
In 1962, the astronomer George Herbig seems to have created one of the best photographs of the Rima Hadley region, made through the 3-m reflecting telescope at Lick Observatory. This photograph was the source of NASA's plans to land humans on the 'plain' between Mt Hadley and Mt Hadley Delta, both near Rima Hadley (Apollo 15 landed there in the summer of 1971). George Herbig's target was not the moon, but... he had to wait until moonset to take photographs of deepsky objects (while waiting, he made 'THE' photograph of Rima Hadley!).

Named after the nearby peak, Mons Hadley.
Number 112 in Debra Hurwitz's Atlas and Catalog of Sinuous Rilles.
Rima Hadley was not part of the original IAU Nomenclature. The name was introduced on Sheet D3 of the System of Lunar Craters maps. Despite the usage popularized by Apollo 15, this feature does not ever appear to have been officially called Hadley Rille. - Jim Mosher
In his informal 1953 tour of Mare Imbrium, Leland Copeland referred to the two hills west of the Hadley rille's northern part as the Gateway Rocks. These were later informally called Hill 305 and Bennett hill by Apollo 15's crew and NASA personnel. The region has also been referred to as the Fresnel Ridge. D.Caes research.
