Mat’s travelogue

Ocean Beach Footsteps

Ocean Beach Footsteps

A beach-goer walks into the sunset on San Francisco's Ocean Beach.

Phantom Ship in Crater Lake

Phantom Ship in Crater Lake

The island is Phantom Ship, one of only two islands in Crater Lake. If you can believe it, this photo has not been saturated at all - the water is that deep a blue.

The setting sun breaks through a small Joshua tree - Joshua Tree National Park

Raven - Yellowstone National Park

Raven - Yellowstone National Park

Like crows on steroids, these large birds play an important role in Yellowstone's ecosystem. Ravens have a somewhat symbiotic relationship with Yellowstone's wolves. They arrive at a wolf kill in no later than two minutes (!) and lead wolves to other scavenging opportunities.

Stay On Your Side, I'll Stay On Mine

Stay On Your Side, I'll Stay On Mine

Two distinct heat-loving micro-organisms, called thermophiles, co-exist in a hot springs drainage in Yellowstone National Park. The heated water varies only a few degrees between the two areas!

Artists Paintpots - Yellowstone National Park

Artists Paintpots - Yellowstone National Park

Some of the fascinating stages of an Artists Paintpots spot. I could sit and watch these guys all day.

Yellowstone Thermophiles

Yellowstone Thermophiles

Looking like something from an electron microscope, thermophiles pile onto anything they can get a hold of in a Yellowstone hot spring.

Colonnade Falls (Upper and Lower) - Yellowstone National Par

Colonnade Falls (Upper and Lower) - Yellowstone National Par

Drops of 35 and 67 feet respectively, Colonnade Falls is a rare sight for Yellowstone visitors. (You have to hike quite a ways - but it's worth it!)

The area along the Bechler River trail is called Waterfall Wonderland for good reason - there's an amazing amount of epic falls in the area.

Willow Flats - Grand Teton National Park

Willow Flats - Grand Teton National Park

Prime moose country, alas none were to be found this afternoon in Willow Flats, Grand Teton National Park.
