2/18: understanding a name

Chris has been looking at place-names adopted from Native American languages; he asked me if there were any near where I grew up in Pennsylvania.  I mentioned some but then wanted to look at a map to see if there were more.  And I found "Wopsononock," which everyone calls "Wopsy Mountain" back at home.  I'm glad to know its fuller name now, "Wopsononock" being a Delaware word meaning "white land."
