I agree 100%+ !!!
Looking at the data from Mars Global Surveyor Thermal Emission Spectrometer (Current & Past) and of past spacecrafts spectrometer readings and reports. It shows
the Mars equator to be warm at times.
http://tes.asu.edu Look at the daytime temperature readings near the equator , which is where Spirit is located (14 S & 175 W). At times
you can see very dark red, which is @ 20C+ that is @ 68 degrees fahrenhect on surface.
The Mars Spirit rover have a Mini-Thermal Emission Spectrometer , which detects the infrared light, or heat,
emitted by objects.
Red is heat from ground, and Sleepy Hollow area is redish, which means heat, the next question is "what is the temp readings?"
Here's the data and current readings of said area....

Don't know..vet out
Wow, that is a great site. Thank you for the link.
I am disapointed they did not include a scale with the mini-thermal emission spectrometer. I am just guessing here, but if there were some kind of moisture mixed with the material in sleepy hollow, wouldn't it show up as cooler than its surroundings?
