I was googling pasque flowers, trying to make sure my memory was correct on these stragglers in the volcanic dust. (They seem to be the seed phases of Western Pasque Flowers.) In doing so, I came across the website of John H. Boyd, III (http://jboyd.net/PacNW07/PacNW07q.html ) which intelligently wanders through Crater Lake, J.R.R. Tolkien, bird species, and Japanese woodcuts.

Boyd uses a Lord of the Rings quote as he departs Crater Lake:

As Bilbo Baggins would say, "It's a dangerous business, Frodo, going out your door. You step into the Road, and if you don't keep your feet, there is no knowing where you may be swept off to.”
