Report 6746: Man has sighting after massive landslide on Highway 50

I think the year was 83 or 84. That year there was a huge mudslide on the south (River) side of Highway 50. I remember because we had to turn around, go back up around Tahoe, and take Highway 80 back to the Bay Area. We were among the first to the slide area, and got out of our truck to look. It was early evening, and  I saw a huge, bi-pedal creature on the slide side of the river. It was on the Tahoe (east) side of the slide, as were we.  It was high on the hill, and appeared to also be regarding the slide. I saw it for about 15 seconds, when it ambled up the hill and out of sight. I have seen many bear, and this was no bear. A bear might rear up, but aside from circus bears, none will walk that way for any length. Even circus bears have an ungainly walk when trying to go on 2 legs. The motion of this creature was much smoother.
