An American Snowdrop Tree blooms in Portland. This may be the first example of the species I’ve ever seen in bloom. It’s quite beautiful.

Columbia River Basalts, intruding into faults in preexisting sedimentary layers created this invasive dike formation along the Oregon coast.

I became familiar with these birds while living in Florida. the swim, body completely submerged, only their necks break the surface. This has earned them the common name of snakebird.

Wild Goose Island sits, diminutive before the crest of the Rocky Mountains. These peaks of Glacier National Park mark the continental divide. The lake in the foreground is St. Mary Lake.

Southwest Portland is home to this beautiful wetland refuge along the Willamette River. The preserve is a smart use of city land in a flood plain. It provides habitat for many regional species, and recreation opportunities for city residents.

Pacific Trillium is a common site in the Pacific Northwest. Most often white flowers dominate. However, while blooms are young, purple and maroon hues are not uncommon. If you’re in Portland in early April, check out the Trillium Festival.

Wanna know where the sun and moon are and/or will be? Then this is the device for you! (Assuming I’m talking to someone alive prior to the advent of the internet.) By moving the interlocking rings, you can predict the location of prominent stars, zodiacal constellations, and more!

This slab of jasper was unearthed in Biggs, Oregon. Rock hounds commonly see images in cuts like the one above, much like seeing shapes in cloud formations. I see a roiling sea here. What do you see?
