Park & Ride at 65th and Ravenna NE, Seattle, 7:00 am. We will meet north of 65th, opposite the expresso store and perhaps two or three aisles north of 65th.

If you choose to drive to meet elsewhere, please e-mail the leader for directions.

We will hike the beautiful Boulder River trail perhaps to it's end and return the same way. This is a luxurious old growth forest trail that passes a number of lovely waterfalls.

Many of the mosses we'll see on this hike are different from those at Discovery Park and Tiger Mountain, the forest being much wetter. This is a good follow-up for those that attended the moss and lichen classes this past fall and this winter as well as for those would like to begin exploring the mosses of Western Washington. On this hike we will concentrate on mosses of wet rocks and riverside boulders and try to learn to distinguish them. Stewart Hougen will be along as co-leader to help us with lichens and mosses. Stewart has created a handy introductory study guide that he will make available to participants. It is highly recommended to print that guide out and place the pages in a small notebook, preferably as inserts in plastic pages. And don't forget your 15X or 20X loupe. Loupes can be purchased in Seattle at the U of W Bookstore. A reasonable expectation would be to learn 4-5 new mosses and lichens. Photographing them with a digital camera or even a phone allows one to review at home what one has seen in the field.
