Promontorium Olivium is the site of the somewhat infamous O'Neill's Bridge. Without access to the original documents the circumstances surrounding this event are a bit difficult to reconstruct, but it seems that in 1953, as the Sun was setting over the western shore of Mare Crisium, science writer John J. O'Neill observed a fan of light apparently emanating from the low spot between Promontorium Olivium and Promontorium Lavinium and spreading to the east. Incorrectly interpretting this as the signature of the arch of a 12-mile wide natural bridge he sent letters seeking confirmation of his discovery to a number of prominent lunar observers of the day, including H. P. Wilkins. Wilkins possibly understood that a lunar bridge would not produce a fan of light, but seems to have claimed to have observed the shadow of a much smaller arch (and the light shining through its aperture) at nearly the same location; observing this both with a 15-inch reflector at his home and with the Mount Wilson 60-in reflector (the later, at least, with a quite high Sun). Wilkins' (south up) Mount Wilson sketch (see Dobbins and Baum, 1998 article in Bibliography) shows a tiny loop to the south of the small crater known in the System of Lunar Craters as Proclus PA (just to the right of the dot for Proclus P in the Lunar Orbiter photo shown at the top of this page -- which is likely at very nearly the same sun angle as Wilkins' untimed Mount Wilson observation). Wilkins estimated the length of his smaller arch to be about 1.5-2 miles, and appears to be trying to show in his drawing that its shadow pattern changes in the manner that would be expected for an arch illuminated by a lowering Sun. With his home telescope he might possibly have been looking at Proclus PA itself, the bowl of which seems to be represented in the Mount Wilson sketch by a dark circle with a bird-like double beak extending to the south. Strangely, the axis of the bird's bill is shown diverging from the axis of Promontorium Olivium at an angle of about 30° when all photos suggest they should be nearly parallel or converging. It is unclear if Wilkins thought his arch could account for O'Neill's extremely broad fan of light when illuminated at much lower sun angles (something that would require some highly improbable reflections from shiny surfaces on the underside of the bridge). According to Charles Wood, Wilkins hinted in the 1954 edition of Wilkins and Moore that the bridge might be artificial, although other articles about the incident claim Wilkins always insisted its was natural. All references to O'Neill and his bridge seem to have been expunged from the final 1961 edition of The Moon, although his name is printed just to the west of the gap between the two promontories on Wilkins' map of Section XII (p. 192), and the name is listed as having been proposed by Wilkins (p. 353)
Just when you think you have seen everything, LROC reveals a natural bridge on the Moon! Who would have thought? Natural bridges on the Earth are typically the result of wind and water erosion -- not a likely scenario on the Moon. So how did this natural bridge form? The most likely answer is dual collapse into a lava tube.
June 5, 2007: Picture this: A spaceship swoops in from the void, plunging toward a cloudy planet about the size of Earth. A laser beam lances out from the ship; it probes the planet's clouds, striving to reach the hidden surface below. Meanwhile, back on the craft's home world, scientists perch on the edge of their seats waiting to see what happens. Sounds like science fiction? This is real, and it's happening today.
December 7, 2005: Every lunar morning, when the sun first peeks over the dusty soil of the moon after two weeks of frigid lunar night, a strange storm stirs the surface.
The next time you see the moon, trace your finger along the terminator, the dividing line between lunar night and day. That's where the storm is. It's a long and skinny dust storm, stretching all the way from the north pole to the south pole, swirling across the surface, following the terminator as sunrise ceaselessly sweeps around the moon.
Never heard of it? Few have. But scientists are increasingly confident that the storm is real.
Well, guess what? Writer Clement was righter than he knew. It appears lunar dust does levitate above the Moon's surface because of electrostatic charging. And the first evidence came almost the way Clement had described.
In the early 1960s before Apollo 11, several early Surveyor spacecraft that soft-landed on the Moon returned photographs showing an unmistakable twilight glow low over the lunar horizon persisting after the sun had set. Moreover, the distant horizon between land and sky did not look razor-sharp, as would have been expected in a vacuum where there was no atmospheric haze.
But most amazing of all, Apollo 17 astronauts orbiting the Moon in 1972 repeatedly saw and sketched what they variously called "bands," "streamers" or "twilight rays" for about 10 seconds before lunar sunrise or lunar sunset. Such rays were also reported by astronauts aboard Apollo 8, 10, and 15.
NASA will tomorrow launch a spectacular mission to bomb the Moon. Their LCROSS mission will blast off from Cape Canaveral, Florida, carrying a missile that will blast a hole in the lunar surface at twice the speed of a bullet. The missile, a Centaur rocket, will be steered by a shepherding spacecraft that will guide it towards its target - a crater close to the Moon's south pole. Scientists expect the blast to be so powerful that a huge plume of debris will be ejected.

I watched another of that guy's videos the "Bird and insect" statues made of gold that he scale built one of and it flew like you wouldn't BELIEVE.. hehe but yeah its a bird or insect.

Great find, but it looks like an natural bridge.
