Quartz and gold Quartz and gold are very different minerals. One is an oxide, one is a metal. One is only a single element, the other is a compound of two different elements. One has a high hardness and is tough to scratch, the other is soft and easily scratched. However, these two distinct minerals are found here together for a very important chemical reason.

Video by Ronan Donovan @ronan_donovan | This is Bearzilla. Estimated to weigh in the 600-700 lb range, this is a really big male for the Rocky Mountains. What's interesting is that most bears in March emerge from hibernation lean and muscular, having burned through their fat stores. But not Bearzilla. I spent a few weeks watching him gorging on several bison carcasses along the Yellowstone River in March. Of the six other male grizzlies coming by to feed, Bearzilla was by far the largest and most rotund. He was also the only bear that was relaxed enough to nap and play near the carcasses. The rest of the bears ate fast and got outta there quickly. In this video, Bearzilla gets annoyed with the ravens, swats a European starling, and plays with his meal. It's a brief window into the day in the life of a Yellowstone grizzly. Video taken while on assignment for @natgeo Hope over to @ronan_donovan for more photos and videos of Bearzilla

I wouldn’t normally post a video but this was one very close encounter on our winter wildlife trip! Bison look slow but they’ve got surprising speed when they want to move!

Finally found a good corner shelf for some large artifacts and others that wouldn’t quite make a frame. Rounded it out with fossils, geodes, crystals, and shells we’ve collected over the years. Got at least 1/50th of our things out of tubs! 😂

Yellowstone really living up to its namesake.

NATURE IN MOTION - Specifically, the perpetual motion one sees in Yellowstone National Park. Highlights from my October visit include Snowy, a three-year old grizzly bear, thermal springs, tumbling waterfalls, and of course, pondering bisons basking in a dust bath.
