Mt. Baker at Sunrise

December 01, 2022


220830-3

Photographer: Marli Miller
Summary Author: Marli Miller

Reaching an elevation of 10,781 feet (3,286 m), Mt. Baker dominates
the landscape of northern Washington. This view, towards the WSW from
near Lake Ann, shows two of the more than 15 named glaciers that
descend in a radial pattern around the volcano: the Park Glacier on
the right; and Boulder Glacier on the left.
Mt. Baker, a stratovolcano, erupted andesite and dacite
lavas from as far back as 140,000 years ago, but its most active period
occurred between 25,000-12,000 years ago. It was during this time that
it built its base and summit cone. Since then, it’s only erupted ash,
although a collapse of one of its flanks occurred some 6700 years ago.
Multiple small events took place during the 1800s and an increase in
gas emissions in 1975 suggested the presence of new magma in the
volcano. These emissions have tapered off through time.
The USGS maintains an active monitoring program at Mt. Baker.
Because of the extensive glaciers, even small eruptions can trigger
devastating lahars (volcanic mudflows), which can flow great
distances away from the volcano. Photo taken on August 22, 2022.

Wafer Thin Moon and Pumpkin Sky

Summary Author: Matthew Chin; Jim Foster
Can you spot the sliver of the crescent Moon? Because it was only about
1.3% illuminated when this photo was snapped, at dawn on June 28, 2022,
it isn’t exactly conspicuous against the pumpkin-colored sky. As night
has now lost its grip, hordes of bats are returning to their caves
(could this be the source of the dark smudge at lower right?) and other
spooky, nocturnal creatures will soon be asleep in their lairs. Photo
taken in Yuen Long, Hong Kong, on June 28, 2022, at 05:12 a.m. local
time.

Basket Stinkhorn

September 30, 2022

Stinghorn

Photographer: Mila Zinkova
Summary Author: Mila Zinkova

Shown above is the Basket Stinkhorn, Clathrus ruber, that I came
upon during a walk in the woods not far from San Francisco, California.
Its odor is repugnant to you and I but is evidently like catnip to
flies. " They flock to her foetid scent, feed upon the
spore-impregnated greenish-black gleba, and soar off, spreading
stinkhorn spores in their wake."

Most often found in temperate deciduous forests, Clathrus ruber
hatches from an egg-like film. At the base of which is a mycelial
“root,” that at this stage has little scent and might be edible to
some. However, it doesn’t take long before its stench is so
overpowering that only a creature like a fly could be attracted to it.
Click here to see a video from hatching to decaying.
