Beautiful Alpine Lakes in the Sierra Nevada Range

Summary Author: Cindy Todd

Blue Lake, shown above at top, is about 3 miles (5 km) from the
Sabrina Lake Trailhead in the Eastern Sierra Nevada’s, part of
Inyo National Forest. But it's a steep uphill climb the entire way.
It’s worth it, thought! Blue Lake just appears out of nowhere and is a
simply gorgeous alpine lake, with nearby granite peaks jutting
up towards the sky.

After camping the night, I hiked to Hungry Packer Lake (bottom
photo). You can see Picture Peak in the background at right center.
The hike from Blue Lake is about 3.5 miles (6 km), however it’s a
relatively easy hike. Along the way, you’ll see several other alpine
lakes before viewing Picture Peak, standing at 13,140 feet (4005 m) in
elevation. Hiking in this area is stunning! Photos taken on August 28
and 29, 2022, respectively.

Summary Author: Stan Wagon

Red Bar Bridge is a remarkable landform found at the head of a small
wash near the bottom of the Moki Dugway, a famously steep road near
Mexican Hat, Utah. This waterfall bridge forms a natural arch
caused by the tremendous flow of water and has dimensions of
approximately 85 feet (26 m) in length with an 8.5-foot (2.6 m) gap.
The arch is composed of sandstone from the Halgaito Sandstone
Formation, which underlies the massive Cedar Mesa Sandstone
Formation. These formations are part of the Cutler Geologic Group
that arose during the Permian period.

Photo details: Sony A6500 camera; 10 mm lens; f/13; 1/800 second
exposure; ISO 400 (first shot), 320 second shot.

iridescent Clouds Observed from Tuen Mun, Hong Kong

October 17, 2022

Photographer: Terry Lui
Summary Author: Terry Lui; Jim Foster

I observed these two iridescent clouds on the same day, June 1,
2022, from Tuen Mun, Hong Kong. The cloud at top is likely an
altocumulus cloud in the incipient stage of formation, and the
cloud at bottom is a pileus cloud. Both clouds show iridescence or
irisation because their cloud droplets are small (perhaps 1/100 the
size of a raindrop) and all are about the same size. The pastel colors
result from the process of diffraction – light waves are interfered
with by the small droplets in such a way that orders of colors overlap
each other.
