I LOVE Yellowstone.. I had the pleasure of work camping in Yellowstone a few years ago and make it a point to return every year. I still find that after my 5 month stint and yearly visits that I have not come close to seeing all there is to see in this 2.2 million acre park. Though my visit this year was way too short, it was a brought back pleasant memories of beautiful flowers, waterfalls, critter watching, beautiful sunsets over the lake and watching geysers explode into the air or slowly bubble and steam.
I find it interesting at how many folks go to Yellowstone, see Old Faithful and the Lower Falls in a one day tour and believe they 'have seen' the park. In my opinion to truly begin to see this park, you have to get off of the tour bus route, take a hike .. even a short one and spend some time away from the crowds. That is where you find the true beauty of one of the most remarkable places in North America.
Yellowstone is truly the gem of our National Park system. It has mountains, rivers, streams, lakes, waterfalls, geysers, mud pots, steam vents, grassland, forest, foot hills, bears, birds, bison, wolves, pronghorn and more. I don't know of anyplace else that boasts that kind of diversity. I hope to one day 'see it all' .... something to shoot for I guess, over my next 20 years.
