Left: Mick Hyde Ina can be spotted in the upper part of the plateau in the center of this frame. The crater near the bottom is Yangel'. The mare areas include Lacus Felicitatis (to the left of the Ina plateau), Lacus Odii in the upper right, and a part of Lacus Doloris in the lower right.
Right: AS17-M-1518 Ina is the D-shaped crater pointed to by the white arrow in this extreme enlargement of the area around the crater. The other IAU-approved names in this small area are Dag, Osama and Mons Agnes.

Ina's remarkable bluish coloration

Apollo 17's orbital color Hasselblads of the Lacus Felicitatis region show very well Ina's remarkable bluish coloration. This blue color is also noticeable on the LROC's WAC Albedo/Color Map, see close-up of the Lacus Felicitatis region:

Ina is the most well-known one of the moon's many mysterious IMPs (Irregular Mare Patches). We don't know a thing about the conditions of the surface of Ina. The Lunar Reconnaissance Orbiter's (LRO's) Hi-Res close up photographs of most of the IMPs look very unpredictable, it's as if IMPs are made of an odd substance which could not support a lander. Or is it just a layer of common regolith upon a sturdy solid underground?
As the Apollo astronauts once said: We barely scratched the surface of the moon. In other words: 99.9 percent of the moon's surface is still waiting to be explored. The IMPs (such as Ina) should be the very first targets on the list of a new project of lunar excursions! (unmanned or manned).

Additional Information

On certain digital lunar atlases, the location of Ina is erroneously located at crater Ideler (the same coordinates and diameter of Ideler). - DannyCaes Feb 15, 2010

Who was Joaquin Miller's "Ina" ?

See page 209 in the National Geographic of February 1969 (that wonderful MOON-article from Kenneth F. Weaver).
I don't know a thing of poetry, but... it would be interesting to find out the identity of Joaquin Miller's "Ina". - DannyCaes Aug 29, 2017
Perhaps it was Ina Coolbrith (1841-1928). Ina Coolbrith befriended the poet Joaquin Miller and helped him gain global fame.
