An interesting groundwater seep...

at the stratigraphic contact between the Cutler and Moenkopi Formations below Adobe Mesa bears some further examination, but it’s a difficult scramble to its location on steep and unstable slopes. Light-colored mineral deposits, likely either calcium carbonate (calcite) or calcium sulfate (gypsum), occur at the margins of the seep.

Peering into the abyss...

of Sevenmile Canyon north of Moab on a spectacular mid-winter day.

An immense pour-off defines the upstream end of Sevenmile Canyon, west of Arches National Park.

The Slick Rock Member of the Entrada Sandstone comprises the vertical walls of Sevenmile Canyon, capped by the Moab Member of the Curtis Formation (Middle Jurassic (174.1-163.5 Ma)). The Windows Section in Arches National Park on the horizon is eight miles (~13 km) distant.

Lying in wait...

with infinite patience at the feeding station this cold and overcast morning, Sharpie sat nearly motionless for about 45 minutes.

Sharp-shinned Hawk (Accipiter striatus).

A milky ribbon of water ice...

covers Castle Creek thanks to the frigid nighttime temperatures, but long crystal-lined canyons in the milky ice open like skylights and reveal the water flowing beneath.

This winter season continues to be cold and very dry. The snowpack in the highcountry is now 80% of the historical median snow water content, but there are still 68 days until the median peak snowpack.

The twelfth successful flight...

and soft landing of the scale model Patriot rocket this chilly but calm afternoon.

The Patriot model rocket after a successful flight to 425 feet (130 meters). The vent holes allow the parachute to rotate on a swivel during descent. Very entertaining.

Historic inscription near Big Bend...

on the Colorado River upstream from Moab commemorates a gold placer operation that occurred 130 years ago. High marks to the person that chiseled this historic graffiti into a varnished sandstone boulder above the river. It’s very well done and endures to this day.

Located on the north side of Utah 128 just west of the bouldering area at Big Bend (about 0.6 mi (1 km)).

R.H. is the likely inscriber, but notice the initials JA are faintly pecked in the upper left.
