Slickrock Country Talk

I'll be giving a presentation at the Bend REI store on February 23 about the Slickrock country of southeastern Utah. The program, which starts at 6:00 p.m., will be a visual tour of Arches and Canyonlands National Parks, and feature the cultural and natural history wonders of the area. I'll be signing copies of my latest book, as well as having some of the others on hand. Hope to see you there!

Living in the Soup - A Central Oregon Inversion

We are living in a soup, more like a cloudy broth brought on by an inversion. The inversion layer has trapped a layer of cold air and fog beneath a ceiling of clouds. Pretty cool as a weather-related event, but you can tell that people are ready for a new pattern.

According to the weatherman from the National Weather Service in Pendleton, a stable, high pressure atmosphere is holding over our area. The inversion is like a pot lid, holding in stagnant air boiling in the pot. During an inversion, the Cascade Mountains block any warm air flow off of the Pacific Ocean from moving the clouds out of the area. Because it is winter and cold here, now cold air flows down from the mountains, creating cold temperatures in the lowlands. The nighttime lows have been in the upper teens and low 20s.

With the cold temperatures and the sun farther to the south, the daytime warming trend is not strong enough to warm up the ground. If it could, the ground would radiate the heat back up into the air to break up the inversion. At the same time, the cold temperatures near the ground are around the same level as the dew point - the temperature at which dew starts to form. That means that the moisture in the cold air condenses and forms fog, freezing fog or very fine snow. You can see this coating on the trees and shrubs in town; they appear to have been sprayed with a mist.

Moving the inversion layer out will take a stronger storm front or upper atmosphere disturbance, which is in the forecast. Although this type of weather is pretty cool to observe, it does pose health problems as the stagnant air holds wood smoke, pollution and other contaminants in for us to breathe.

Locals know that to get out of the gunk, they have to drive to higher elevations like along Century Drive towards the Mt. Bachelor Ski Area. At a certain point, they pass out of the cloud layer and into the sunshine. And for some, into a much better mood.

Ocean Waves

Yaquina Head Lighthouse



Wild weather framed a Thanksgiving trip to the Oregon Coast. Gale force winds, sheets of rain, a quilt of black and blue sky, and eerie moments of calm winds punctuated the weekend. High surf warnings impact beach walks, but create spectacular spray as the waves crash into the rocky headlands. Even the downpours provided either photographic opportunities or periods of indoor exploration.

Colony Rock
We took the free 'Back Wing' tour of the Hatfield Marine Science Center to learn about the behind-the-scenes operation of the center. Pretty fascinating process that the aquatic creatures go through prior to their release into the exhibits or back into the wild. Hopefully, one contact will turn into a personality profile piece, while the concept of what to do on a rainy day at the coast will also manifest into a short article.
The Yaquina Head Lighthouse also provided us with an elevated view of the ocean activity. Waves crashing over Colony Rock produced "Oohs" and "Aahs" from the crowd. Brown pelicans, common murres, gulls, and a few surf scoters passed by below the observation deck. They too were taking advantage of the proverbial calm in the middle of a storm.
This just goes to show you that there is always a story, like a cloud's silver lining, to be found no matter what the weather. Queries are out; stay tuned.

Walking the Wonderland

Spray Park


I hiked the 93-mile Wonderland Trail (WT) in Mt. Rainier National Park this September. Incredible and awesome are understatements. I had an 8 day permit and hiked counter-clockwise starting and ending at Longmire. The majority of hikers that I met were hiking the trail clockwise, but everyone gets in their 23,000 plus feet of elevation change no matter which way they go.

The hike was part personal celebration and part work project. Although my book contract for another Pocket Guide died on the production table, I can not fault the publisher. Disappointed, sure. But what I learned from the hike is to take it one step at a time. So now I'm working on some articles about hiking the WT.
