It's orange, it's goo, and it started washing ashore Wednesday night. That's about all the remote Alaskan village of Kivalina knows so far about the mysterious substance blanketing its harbor and beaches. Tests have been conducted on it, but all that's been determined so far is that it's not a petroleum substance and it's not man-made, reports KTUU. Curiously, the goo has also shown up in some residents' rain buckets. One resident says she didn't smell anything odd when she dipped her hand into it. The village is requesting that an algae expert investigate further. (More Alaska stories.)
