Bison are plentiful in Yellowstone. Though the color is "off", it portrays the size of herds. You can see babies, etc. Bison are sloooow-moving animals. They *look* super-tame but there are signs(everywhere) that warn about agressiveness.

This was rather common. Animals(bison) like thermal activity(esp. in winter). You are looking at a fumarole. There are 3 types of thermal activity, fumaroles, geysers and mudpots. Fumarole emit steam. Most of them are noisy and sound like loud-heavy exhaling. Most thermal activity has a distintive sulphur smell. As a last resort, animals avoid the cold Yellowstone winter by warming-up at thermal areas. A big dose of sulphur is poisonous!

This is a typical valley in Yellowstone. (40-65 degrees 9/2-9/14 wind 12 humidity-low)

Geyser cause it erupts(spouts water). Many geysers erupt every couple years and others they can't even predict. Hence Old Faithful has earned it's name. One thing ALL geysers(thatI saw) have in common boiling water. Arrow points to boiling water. Weirdly, often you can see into the ground. Bill was funny(I swear, I was like this). He photographed his first geyser for almost an hour and waited(lol). There are thousands of them in Yellowstone.

It is so bizarre to see thermal activity in the midst of wilderness! I commented that "Rangers must be able to distinguish fire-smoke from fumaroles". As far as people, we came after season(on purpose) and though many of these spots are popular the sheer emmensity of Yellowstone(1/12th of WY) helps to decrease congestion.

Mother Bison and baby drinking. Yellowstone was very dry but there were numerous twisty-rivers and streams thoughout the valleys. Also Yellowstone Lake is large(largest high-altitude lake). Guessing:about 1/4th the size of lake Okeechobee.

Nice ....fumaroles with a Bison herd with river.

We were gonna take a half-worn trail through one of yellowstone's valleys when I spotted ...this!!!! THERMAL ACTIVITY right below the thin-soil. Immediately we backed away and stayed strictly on the trail. I thought we were far enough away from this hot stuff. Alllll around thermal activity there are signs warning visitors of the dangers of surrounding thin earth.

Though bison are mostly in herds, we saw 10-12 lone bison. I pondered "What did he do??". Park ranger told me that bison herds are matriarchal and once male bison perform their duty, they are often ostracized. These "loners" are all males.

Yellowstone river(?) becomes Yellowstone Lake - you can see the smoke from the Idaho fires effecting visibility. Actually I *might* see a little bit of smoke in the sky.

Can you see an animal in this pic? (this is how it started out - movement gave him away)

Yep! A Mule Deer. The most distinctive difference between mule deer and elk is the size. Grown elk "tower" over mule deer.

We stayed at Canyon Lodge Cabins for 3 nights. This mule deer was within 10 yds of our cabin ...and for 1.5 hrs he roamed and nibbled.We could even watch him from inside the cabin. Hence Bill got several great shots. For a photographer, lighting means ALOT. Notice how the sun light falls on the grass in one photo. (not on the animal >>Rats!) These cabins were surrounded by woods. I LOVE that about Yellowstone & Teton ...and the wildlife!!!

Mule Deer and a ray of sunlight.
