The only obstacles we encountered while paddling up the canyon towards the crater were a two-metre high rock wall that we had to portage over near the beginning of the canyon and a short section near the end of the canyon closest to the crater where it became too shallow to paddle the canoe.
The crater and the canyon probably began as a fault in the bedrock.
The remaining portion of the craters edge is a steep slope composed primarily of large boulders.
Armstrong was the first to step onto the moon's surface, uttering the famous phrase "That's one small step for a man, one giant leap for mankind." After retiring from NASA in 1971, Armstrong was a professor at the University of Cincinnati for nearly a decade.
Armstrong's first words on the moon are sometimes quoted as, "That's one small step for man, one giant leap for mankind." Armstrong maintains that he said "for a man," and that is how the statement was reported the next day, but tapes of his words are inconclusive.
Armstrong was especially happy for this as he was prone to motion sickness as a child and could experience nausea after doing long periods of aerobatics.
