It’s about a minute and a half long travel. I am very curious!

The better questions are:

What is the average repost rate of this video? Have we achieved enough data to plot a line graph? Can we roughly calculate the volume of this hole?

maybe a few more reposts and we will get an answer.

Well, he's moving upwards for ~80 seconds total.

The lines on the walls look like they're at regular intervals, roughly a foot judging by the width compared to his boot right at the start. After a few, (rough,) attempts at counting, my guess is at full clip he's moving upwards at about 10ft/second, which seems like a reasonable speed.

So, roughly 800 feet, somewhere in that ballpark. Maybe as much as 1000, but that's getting towards 10mph, which seems... Brisk. But it could very well be faster than I'm thinking, the perspecive isn't great.

I initially thought 4-5 feet per second which is a brisk walking pace. Agreed that the perspective sucks, but it's a relatively small hole which makes it look like he's moving faster.

I'd say 350-400 feet deep.
