Ice in the stream

Out walking recently, I found intriguing ice patterns in a small stream. My guess is that the stream level was dropping and ice formed at different levels as it fell. The picture was taken under a footbridge, which shows as dark bars reflected in the water. I don't always love frigid weather, but this was a good morning.

Woodworking

After winding up my folding desk efforts, I've made a few more projects.

This is a shaker style table with a birch plywood top, red oak aprons, and laminated pine legs.

A yard sculpture titled "Blue Tensegrity", after Buckminster Fuller's term for structures using isolated compression elements and tension elements. Made of two-by-two pine construction lumber and one-sixteenth inch stainless steel cable.

Links to plans for folding desks are at the end of this post.

Update January 31, 2021: Someone asked for photos of desks, so I'm posting a few here.

Update January 16, 2021: Plans for the modified folding desk are at the end of this post, together with the original plans. Feel free to add comments and suggestions.

Update January 11, 2021: I have made modifications to the folding desk, and I will revise the plans shortly. In brief, the changes are (a) switched to non-mortising hinges because they are lighter and fold slightly flatter than door hinges; (b) removed plywood cross-braces and replaced them with 2 by 2 braces mounted in-between, rather than on top of, the legs, reducing weight and allowing legs to fold flatter; (c) removed about 3 pounds of material using cutouts in the back panel.

Calf Creek, Escalante Canyons

East of Bryce Canyon and west of Capitol Reef national parks lies a large rugged region known as Grand Staircase-Escalante National Monument. A mosaic of BLM and state lands covering more than 1,500 square miles, it was the last area in the continental U.S. to be mapped. We had just one day to see some tiny portion of it. As always, a visitors center gave us great advice: we decided to hike Calf Creek in the Escalante Canyons area. It's a "moderately strenuous" in-and-back hike totaling six miles, with a 120-foot waterfall at the turnaround.

As in much of southern Utah, the rocks and topography are spectacular.

After three miles uphill in warm weather, through a lot of deep sand, the waterfall and pool were a very welcome oasis.

You ought to give Iowa a try

Before our latest cross-country trip we had never spent time in Iowa. We didn't know what we'd see, except the Andy Goldsworthy sculptures near Grinnell and in Des Moines. I assumed in my ignorance that Iowa would be flat. It's not. And the rolling hills were lush with corn in mid-September, making for lovely landscapes.

We also visited the Neal Smith National Wildlife Refuge, which preserves tallgrass prairie, oak savanna and sedge meadows. It too was very beautiful, and we enjoyed their educational center as well (did you know that some prairie grasses have roots 12 feet deep?). Wild sawtooth sunflowers combined with grasses and other wild plants to form a lovely mosaic. They use fire, seeding and, in one 700 acre enclosure, bison to reconstruct and preserve the prairie ecosystem. Very cool.

Bryce Canyon National Park

Our national parks are treasures. Each has unique and awe-inspiring features. So I hesitate to call any particular park "most photogenic", but Bryce Canyon certainly would make the short list. We were fortunate to spend two nights in the park (Susan reserved one of the last rooms months before we traveled) which enabled us to see more of its moods. Lovely weather prevailed before dawn and beyond.

The park is known for its hoodoos, the vaguely person-shaped formations that result from weathering and erosion of rocks rich in calcium carbonate. The park experiences 200 days a year when nighttime temperatures are below freezing and daytime temperatures are above. All those freeze-thaw cycles contribute to the erosion.

Our only "bad" weather was a rainstorm that conveniently occurred during our dinner in the lodge restaurant. The next morning brought a view of a sparkling stream in the bottom of the canyon and stronger scents of pine at the top.

The canyon rim is above 8,000 feet, giving spectacular views of the canyon and the rugged Grand Staircase-Escalante National Monument beyond.

Three Arches

If rocks are the bones of Mother Earth, then we've seen a glimpse of her ribs. Arches National Park in Utah has more than two thousand arches, and we saw only a few during our single day there. The massive sandstones of the region were uplifted and fractured into vertical "fins" like the one Susan is about to hike up (look closely to see two other hikers near the top; hikes in this area aren't recommended for those "uncomfortable with heights". It was a little bit scary).

After the fins were exposed, erosion carved them into many shapes, including arches. The largest we saw was Landscape Arch, which suffered a large rockfall in 1991. These monumental forms are only temporary.

Other arches aren't as large or graceful, but are still intriguing.

And Arches Park is not the only place with them. We hiked to this one in Capitol Reef National Park, also in Utah. It's a strong sandstone above a more-easily eroded stratum, now gone.
