The dark phenocryst in the center of the image shows clear zoning. The groundmass consists of orthoclase with minor plagioclase, biotite, hornblende and augite.
have seen me out on my RadRover 5 nearly every day the last couple of weeks, and I snapped this panorama at the midpoint of my 17.5 mile ride today (~1,600 feet vertical). Always fun and enjoyable.

with Apex Expeditions, having just been asked to co-lead a two-week long itinerary exploring Iceland in the spring. Volcanoes and glaciers and stunning landscapes!
Here’s a full description of the tour: Apex Expeditions - Iceland in Spring 2022.
having now dried out from a wet spell in January.
at Boca Chica, Texas, also known as Starbase, where SpaceX has stacked the largest and most powerful rocket for an orbital test launch in the coming months. The booster and Starship seen here is taller than the Saturn V that heaved Apollo to the Moon, with more than twice the thrust and 100-150 tons of payload capacity. WOW.

Elon Musk is determined to make humans a multi-planetary species, and this is the launch system that will take us to the Moon and Mars. Learn more about Starship here.

Note the translucent nictitating membrane covering the eye in this image, the equivalent of a “blink.”
chase a soaring raptor overhead this afternoon. This Red-tailed Hawk (Buteo jamaicensis) is being abused by several pesky Western Ravens (Corvus corax sinuatus) in the images below.
overwhelmed the feeding station this afternoon, with more than 50 in number. Here are just a few.
Pinyon Jay (Gymnorhinus cyanocephalus).

Western Raven (Corvus corax sinuatus).
Pro tip: Shoot these active characters near a dumpster!
for the hawk to lift and carry away, this raiding rodent is pigging out daily on bird seed. The cheek pouches appear to be at capacity in the image below.

of the death of Sir Ernest Shackleton.
On the evening of 4 January 1922, as his ship - the Quest - lay anchored in the Grytviken harbor on South Georgia, he wrote his final thoughts in his diary: "A wonderful evening. In the darkening twilight I saw a lone star hover, gem like above the bay." Sadly, later that night, he succumbed to a heart attack and died in the place he loved most. RIP.
I used an astronomical charting program to determine, for that night in North Cumberland Bay on South Georgia, the star he likely saw was either Sirius or Canopus, the two brightest stars in the evening sky.

is huge hit with my feathered friends. The 120V-50W unit maintains access to water at temperatures well below freezing. Highly recommended!
The overnight low last night was 3° F (-16° C) but the water remained open, with a narrow icy shelf around the periphery of the metal basin.
