Cape Royds is on the west side of Ross Island, to the north of McMurdo Station, and at the foot of Mt Erebus. It is home to an Adelie (Uh-DELL-ee) penguin colony that has had difficulty in recent years because of the mega-berg B-15 having indirectly required the penguins to walk too far to feed.
Cape Royd's is also the site of Shackleton's Nimrod hut, built/used from 1907-1909. Here's a good website about the hut with more photos: antarctica2000.net/gallery3/gallery3.html
