On the west side of Yellowstone Lake is an interesting and colorful area called West Thumb Geyser Basin.  This area is one of the many active geological areas in Yellowstone National Park.  We spent several hours there along with hundreds of other visitors.  This is a very popular area in the park.

There is an extensive boardwalk that winds around, up & down the lake shore.  (The surface of the land, here, is very delicate so it is a must to stay on the boardwalk.) It gives a view of the lake where geyser holes are visible through the crystal clear water.

Flowing into the lake are streams of minerals and microbial mats (microbes that thrive in the hot mineral rich environment) that are pouring out of the hot pools that are all about the area as you move back away from the lake.

The colors here were a prelude to the colors we would see in other areas of Yellowstone.   I was drawn even more to my favorite color, aquamarine, which is the color of the hottest pools in West Thumb. The bright orange flow is actually coming from a beautiful aquamarine pool.

My favorite pool was, the all aquamarine, Abyss Pool.   This pool is very hot and very deep.   I could not stop making images of it!

I was drawn to the contrast of the white edge with that intense aquamarine color!

As we approached the junction in the boardwalk that lead back to the parking lot we saw this series of pools that were milky aquamarine instead of clear.

Our visit to West Thumb Geyser Basin was our introduction to the sights, sounds & smells of the very active geological area that is Yellowstone National Park.  Much more to come in future installments.  But our next stop is a peaceful pond with an amazing view of the Tetons.  Part 3 will be coming soon!

That is all for now!
