Explain the DOWNWARDS mountain peak shadow at Sunrise

I was challenged in a discussion with someone, who believes the earth is flat, to explain a video where Mt. Rainier's shadow appears to be cast down as seen from the summit.

There are plenty of images from below Mt Rainier showing the peaks shadow cast on the underside of clouds, but none taken by mountain climbers at the summit. The flat earth argument is, what's seen below the mountain is really the peaks shadow cast on top of the clouds.

The peaks shadow at first light is indeed angled up, but due to the shallow angle, like horizon drop from high altitude, can not be perceived without a reference. Using the moon as a half degree reference in the photo below, the shadow is about 2.5° degrees above the cloud tops.

I made this scale Mt. Rainier drawing illustrating the peaks shadow at sunrise.


At 15° per hour it takes about eight minutes from the time the sun first appears above the horizon at the summit, until it's above the peak. This is the time the peaks shadow can be seen cast on the under side of clouds as seen from the ground, but from the climbers point of view, this shadow is in front of, not above them. It's also worth noting the widest part of the shadow is being cast by the wider part of the peak below the climbers, and does not rise above eye level until it's many miles away, where it's apparent size is diminished due to perspective. The drawing is a couple minutes after sunrise, when the shadow is angled up 1.5°

For those interested, the bunk's original source appears to be from a 16 minute YouTube video by p-brain titled:

Found this awesome video posted in the comments section under one of p-brane's videos. Instead of ending the debate, it appears to have been ignored by everyone.

I'm confused. Where is the video where the shadow appears to point downwards? It certainly isn't in the first video posted in the OP.

It's the first video, and I agree the shadow doesn't appear to point up or down. The FE argument is that on a globe earth, at first light you would see the shadow pointing up. Their evidence is really the lack of any photo or video showing the shadow cast on the under side of clouds as seen from the top of the mountain.

Picture I took using the Dioptra theodolite app on my last flight:

Captured the 'Belt of Venus' showing the Earth's shadow angled up.

Also with wide angle lens:
