Vagabonding on Dangerous Ground: Putting on a Happy Face at Dismal Nitch and Cape Disappointment

Waikiki Beach at Cape Disappointment. Yes, the cliffs are basaltic like those in Hawaii, but the spot was named for a Hawaiian sailor who lost his life here in a shipwreck (one of many). How does a place get a name? Cape Disappointment and especially Dismal Nitch seem to just scream to tourists to "please visit us". Show More Summary

The Skyline median trail

My latest outing took me to what I’ll call the middle part of Skyline Boulevard, the part where the road is divided. Starting at Skyline High School and going south for about 2 miles, a footpath runs in the median. It’s a hidden gem. This is the nearest thing Oakland has to a long walk […]

Vagabonding on Dangerous Ground: "This Dismal Forest Prison" and Other Problems Exploring the Northwest

One of the things that really struck me as we went vagabonding up the Cascadia Subduction Zone last month was how rugged the landscape was. There is a topographic consequence to traveling or living onshore of a convergent boundary. In the long term, the land is pushed upwards into mountains, mountains that in many cases slope directly into the sea. Show More Summary
