The northern tip of Olkhon Island is Cape Khoboy and from it you can see the lake as far as the horizon north, and you can just make out the eastern shore of the lake from atop the cliffs here. Probably 60 km away.
The lake is 646 km long and 79 km at its widest. It has a max depth of 1.7 km, but has 7 km of sediments in the bottom, so you could submerge Mt Everest to the rock bottom. It contains 23,000 cubic km of fresh water - 1/5 of the world's liquid fresh water. It's over 25 mill years old, the oldest in the world and is formed by a rift in the Eurasian Plate. It has hundreds of rivers flowing in, but only one going out - the Angara River that goes through Irkutsk.
Most of my pics at the Cape were panoramas ( which won't load to AFF) or were taken with my good camera, and I'm posting this from my phone, so I might do a JohnM and post some better ones later.
Most of the non panorama ones on my phone had this galoot in front of the view. We could see snow capped ranges in the distance and could just see the eastern shore of the lake.
Looking north up the lake.
Looking down the east coast of the island.
Odd thing was the lack of birds. Seagulls, yes, and some raven looking things, but virtually nothing else. Nothing on the cliffs that I could see. I did see a Baikal teal ( looks like a duck) with my 100x zoom in my camera but that was it.
Oh, and the prized Baikal seal? It's a bit of a hoax as far as I can tell. Only really present in the North of the lake and hardly ever seen down this way. Then, it may be a head bobbing in the distance.
While we were taking in the sights, Alexander was making lunch ...
