Assuming melting snow is *one* method of creating gullies, we might be able to use the CRISM ability to detect water frost/snow on slopes as a means to search for them.
I assume the detection of the infrared signature of water by CRISM can be automated. Then would we have the software set a flag when it is detected in the range of 30 to 70 degress north and south of the equator, where the gullies are found.
Then we would look for gullies at those sites in past MGS images. We can't use MGS now to look at those sites for future gullies, but we could compare them to later HIRISE images of the same sites. There might also be characteristics of these gullies in a single image that would suggest they were very recent. Also, we might be lucky to have MGS images of some of these sites both before and after past frost/snow deposition.

Might provide an automated way to seach for new gullies.
