Nice shots Patrick and don't fret about the color, the crater itself is not particularly colorful. Not at all like Upheaval Dome. Although my photos didn't show it well either, it was more "green" (what is it with green on this board hehe). It wasn't a pretty green, more of an alkaline green tinge - on the floor of the crater. None of the photos, yours or mine , have captured the visual impression captured by the human brain. The outside of the crater rising off the desert floor, the depth or the width of the crater on the inside. If 1973 was the last time you w ere there, you wouldn't recognize the place! The visitor's center is now a lot bigger and all red brick. A nice, albeit small museum for people to stroll through - hands on, a Subway for eats, and a large souvenier shop. T hey are installing an elevator from the parking lot to the museum level. Admission is pricy - $16. After driving to the middle of nowhere you get pinched. Is Upheaval Dome accessible? It would be a unique experience to stand inside a crater, particularly one so intricately complicated. Kurt's and Brent's pictures are very impressive. The diffe rent perspectives show why the origin is contested. From the ground the salt dome theory is apparent, from the air, the entire site makes the impact theory stand out. Shoemaker (1998) pointed out there is no salt, residual or otherwise, near the dome.
