Fossilized crayfish burrow casts...

found in an outcrop of the Triassic-age Chinle Formation near Moab, Utah. Around 200 million years ago this region was a low-gradient alluvial plain, populated by large crayfish belonging to ichnospecies Camborygma eumekenomos based on burrow morphology.

Note the vertical tubular structures cutting across the bedding. Red pen for scale.

Architectural morphologies of different ichnospecies of Camborygma with respect to position on the floodplain and depth to the water table (from Hasiotis and Honey (2000)).

With an eye canted skyward...

toward the gathering storm, this large and flamboyant sparrow is wondering when will winter be over?

Spotted Towhee (Pipilo maculatus).

UPDATE: More than three inches (7.6 cm) of snow fell overnight from another winter storm, confusing more birds at my feeding station.

Frowning Western Meadowlark (Sturnella neglecta), not enjoying the new snow.

Dark skies shattered...

by the vulgar outdoor lighting at the Red Cliffs Lodge located 14 miles northeast of Moab, Utah. The owners/operators are apparently completely oblivious to the beauty and majesty of the night sky.

Guests staying at that lodge will miss spectacular night skies such as this seen from my desert retreat this evening.

Riding out the storm...

but staying close to the feeding station while fluffy snowflakes fall. This round of moisture puts the La Sal Mountains at well over 200% of the median snow water content for this date.

White-crowned Sparrow (Zonotrichia leucophrys).

A magnificent wintry wonderland...

at Bryce Canyon National Park, freshly dusted and dressed with snow from a recent winter storm.

The iron oxide-rich Eocene-aged Claron Formation takes on a luminous quality due to the soft reflected light.

Hundreds of hoodoos stand as sentinels on the snowy landscape.

The Henry Mountains and Waterpocket Fold catching the last rays of the day.

It was a leisurely exploration...

on a delightful winter day with two friends in Gold Bar (Culvert) Canyon west of Moab. A continually ascending trail tops out at Gold Bar Arch, also known as Jeep Arch, after two miles with stunning views of the distant snowcapped La Sal Mountains.

Gold Bar Spire is a prominent landmark on the trail.

The opening of Gold Bar or Jeep Arch is about 45 feet (14 meters) high and about 66 feet (20 meters) wide.
