I launched my first model rocket as a gray-haired adult on Christmas day last year, and these launches bring the year’s total to 103 liftoffs with only two failures (a CATO and a lawn dart). Bigger rockets. Neater gadgets. Huge fun.

and another spectacular winter day on tap, I took advantage of the continued mild weather and headed out to Moab Brands for a terrific afternoon bike ride. Few others are out and the trails are in perfect condition. Here’s a self portrait.

Any one of these lower cost and more environmentally friendly low-water crossing designs would have worked just fine at this small and usually dry stream crossing: Chapter 5 - Low-Water Crossing Types.
comes to a close in three days on the winter solstice and the extended forecast is for continued dry conditions with moderate temperatures. The Old Farmer’s Almanac is predicting that “precipitation and snowfall will be average or above average throughout the Intermountain Region. The snowiest periods will fall in mid-November, early and late January, and mid-March.” We shall see.
Another vibrant sunrise this morning above the La Sal Mountains. It’s good to be a morning person.
The snow water equivalent in the snowpack has flatlined since late-November, now just 121% of median.

This Upper Pennsylvanian-age (~300 Ma) carbonate unit crops out as a cliff former in very few places in the Moab area, seen in the image below as the grayer strata beneath the paved bike trail across the canyon, captured from a high vantage point on the Rusty Spur mountain bike trail.

Also, these launches push me over the century mark, now having sent more than 100 model rockets skyward this year. Huge fun.
