Actually, I was referring to how fast the adults can move, but I'll bet the cubs can really scoot when when they want to, too.

As far as campsite location is concerned, let me give you an excerpt from the Army survival manual. "Ideal sites for shelter differ in winter and summer. The choice during winter depends upon protection from the wind and cold and nearness to fuel and water. In mountainous areas, you must consider the danger of avalanches, rock falls, and floods. you should choose a site during the summer months which is relatively free of insects and near fuel and water. As a protection against insects, it is better to select a site on a breezy ridge or in a place that receives an onshore breeze. Sites in forests and near rapid streams are desirable".

I don't know that I'd necessarily camp halfway down the hill. Depending on the location of fuel and water, another location might be better. It might be sufficient to just be on the lee side of the ridge or hill. Be careful that you don't locate your site in a drainage area on the hillside. You don't want your site to be flooded if it rains.

For what it's worth, in the winter, the East and South sides of a hill will recieve sunlight before the other sides, so they may warm up the fastest (that would be East and North for those south of the equator). Keep the prevailing winds in mind, though, and try to stay shielded from them. I was on a deer hunt once, and had a stand on the West side of a ridge because I didn't want to be blinded by the sun when it came up. I was also about halfway down the hill, as it was about the best location on that hill. As it turned out, the sunlight didn't reach me at all until 10 or 11 o'clock, and I froze my butt off most of the morning while cold air from the valleys behind me poured over the ridge and down my collar.
