Lift-off...

of several model rockets this afternoon, with a digital flight recorder onboard. The rocket engines have gotten a lot bigger, and the gadgets have gotten a lot cooler, since I was a kid. Fun beyond words.

Red Max launching on a C6-5 engine.

Red Nova lift-off on a D12-5 engine.

Arcas soaring on a E12-6 engine, achieving more than 1,600 feet in altitude at apogee!

Flight data as recorded by a Jolly Logic digital altimeter. Data is the new bacon.

A Christmas launch...

of a model rocket, my first in 55 years, went off with a satisfying woooooosh! Just as I remembered it as a fledgling rocketeer in my youth. Priceless.

Second launch of the day, on a C6-5 rocket engine, lofting it to more than 1,000 feet in altitude. Recovery was by parachute, landing 305 feet away from the launch site.

A third launch, on Boxing Day. Woooooooooooooooosh!

The last rays of the day...

UPDATE: This storm elevates the snow water content in the La Sal Mountains to 88% of the historic median.

A "Dark Sky Community"...

shows dedication to the preservation of the night sky through the implementation and enforcement of outdoor lighting ordinances, engages in dark sky education, and enjoys citizen support of dark skies. Our tiny town of Castle Valley, Utah has finally been so designated by DarkSky International and the formal announcement will be forthcoming after the holidays.

An unusual artifact...

has been left in the high desert below Castleton Tower yesterday, its purpose a mystery. A well-beaten footpath winds about 100 yards/meters from a nearby jeep road to this triangular wooden arch, tall enough that a person could walk through its opening. A small fire ring and several log rounds lay further down the path.

I’ve reported this discovery with images and precise location to the local BLM office in Moab. I’m hoping they will dispatch a crew to inspect/clean/reclaim this disturbance to the landscape.

Despite its volcanic appearance...

resembling a cinder cone, Round Mountain is most certainly NOT volcanic in origin. It does indeed consist of igneous rock, but in an intrusive body that cooled and crystallized while still under the cover of sedimentary strata, now being exposed by the subsidence of the Castle Valley salt-cored anticline and through erosion.

Oh, yeah, it was a very nice afternoon for a ride.
