Default Enormous Cave near Spirit site?

About four kilometers to the SE, in the Columbia Hills, is what looks
like it could be a gigantic cave. Check out this huge image:

Be sure to click to maximize the image. It could be shadow but I
don't think so. It looks like it might have been an impact into the
side of the hill. This looks like a very good end mission goal.
Although a solar powered rover might not feel too welcome in a cave.

Thanks for these references. However as this 4.5 meg .gif file is beyond
my meager resources, is there a .jpg version or a much smaller .gif?

Being a caver, I tend to recognize "cavish" features and this is not
an obvious one. I have seen far better candidates on Mars where flows
obviously end in "sinks". I'd like to see some analysis of rock type
in such features.

I take my kids caving and tell them of the adventures they might have
in exploring lava tubes on the moon or the caves of Mars.

Thanks for the picture link. Based on what I've ready, 4.5 Km would be too far
for the rover to travel in its lifetime on the planet.

They're looking at maybe 200 sols for each rover total. They *might* get to
the hills with spirit, but they don't sound all that confident. It is a very
rocky area in Gusev crater and I suspect the going will be far too slow to get
more than 1.5 km in the total life of the rover.

Opportunity has a better shot at going a long distance simply because it has
few rocks in its way. It can probably travel more in a day than Spirit can in
5 days.
