The hyenas sound scary to me, too. One thing just jumped out and bit me, though.

Farther south, at about the latitude of Mongolia, "there are hundreds and hundreds of [human] archaeological sites that go back 50,000 to 60,000 years ago," he says, but just a few degrees north and the sites are no older than 12,000 years.
12K years ago was near the beginning of the last/current inter-glacial period. If Siberia is cold now, what was it like during the glacial period?

It may not have been just the hyenas. You need it cold enough to keep a lot of ice in the glaciers, exposing the land bridge. But you can't have it so cold that you can't get from Mongolia across Siberia to the land bridge.

plus if that's cold, with frozen glaciers as far as the eye can see, would you make a trip across the land bridge not knowing what was on the other side or if there even was another side?

think how incredibly brave or desperate you would have to be to make such a trip.

An excerpt from The World of the American Indian (National Geographic Society), that I mailed you, concering how one might deal with an animal as huge as the hyena Sabertooth has provided pics of:

Boxtraps made of rock, pitfalls dug in snow, and deadfall traps caught larger animals such as foxes, wolves - even a few caribou. To catch a wolf, Eskimos occasionally used what one explored called 'the most fiendish trap ever devised' - sharpened splinters of caribou bone set into ice and smeared with blood and fat. When a wolf licked the bait, it slashed its tongue, and, goaded by the taste of its own fresh blood, kept lapping until it bled to death.

Something that huge, I can't see taking down with ones' hands or even spears, hunting them in a group!
