Sorry to bend your pick. Sometimes Snopes is right, and their analysis seemed objective. Prove them wrong. I'm not the only person here who thinks this is a hoax.

As for pyramids, there were some noteworthy formations on Mars that fell under the same concept, but were later dismissed once better imagery was available. Of all the possible shapes that mountain peaks can have, a pyramid is one of them (e.g., the Matterhorn). Remember that the ice cap is about 2 km thick, so we would be seeing only peaks, not entire mountains.
