… and river flowing below at sunset with traffic. Along the Sacramento River is downtown
Sacramento’s skyline, its distinctive yellow tower bridge spanning the river at sunset facing
east, the UAS moves laterally and backwards as cloud colors fade after the sun has set.

Active geysers vents huge amounts of water vapor in the morning sky next to a flowing river. The
plume ranges from bright pink to gold and ranges in brightness due to a cloud off-camera blocking
the light momentarily.

Winter on Crater Lake: the snow covering the landscape is fresh. The vast lake is not entirely in
the shadows of the clouds, as a break in the layer of thick low-level cover reveals light on the
lake. The turbulent winds blow on the water, making their marks on the surface as they travel,
along with the shadows. Blue sky patches are slowly covered by dawn clouds, which clearly
precipitate on the opposing side of the caldera, near Wizard Hat Island. The ridge that comprises
the crater’s rim, a drop of hundreds of feet, is a winter forest.

Even the snow of the foreground is pink from the ambient light of the clouds. A fiery canvas
ablaze with the day’s last minutes, streaks of vibrant crimson and passionate pink ignite the
western sky. Below, a tranquil expanse of water mirrors the celestial drama, reflecting hues of
rose and lavender. Silhouetted pines stand sentinel along the snowy banks, their dark forms a
stark contrast to the luminous horizon. Distant, snow-capped peaks fade into a soft, ethereal
blue, a gentle boundary between earth and the incandescent heavens. The snow continues in the
distant mountain Mt Tallac (far away and at right).

27 seconds and 23 frames.
Altocumulus Castellanus are here in the top half of the frame at sunset. Being brilliantly
shined upon, they range in color from Grapefruit to shades of pale pink and sharp purple, and
the clear areas of sky remain blue, comprising two thirds of the sky. The bottom half has Lake
Tahoe, a boat makes an inquisitive entrance and exit, and the water moves with gentle, lapping
waves. The other side of the expansive lake is the east sky, with more clouds the further
observed.
Time-lapse length (30 fps):
9 seconds and 9 frames.
Pines and other conifers are framing the sky on all sides of the scene in the early morning above
Lake Tahoe, which is surrounded by a forest, and blanketed partially with a fog layer. The sky
quickly brightens as high clouds and an airplane contrail turn all the colors of sunrise. The
ground is snowy. A similar clip exists.
Time-lapse length (30 fps):
38 seconds and 4 frames.
In the distance over Lake Tahoe, a fog bank is rolling. In the sky, clouds and crisscrossing
contrails are illuminated around 40,000 ft in the morning sun, when colors change fastest (with
the exception of dusk). The chardonnay yellows of the horizon and bluish-purple of the deep sky
this dawn are on display.
Time-lapse length (30 fps):
7 seconds and 11 frames.
The Yosemite River flows through the scene of many steaming geysers that span the frame. The
mid-level sunset clouds catch the light of the sunset, while the river reflects their light.
