But it's only 'cause I am peddling along the shoulder of the information highway on a dial-up connection. Yes, I know, I hang my head in shame.

I enjoyed your site. What I've seen so far is a good source for mars geology info. Your discussion of the cemented joint surfaces (hedges) was very nice.

Since you also had an interesting article about polygons, I thought I'd pass along a great experiment for creating polygons: make a slurry of water and corn starch, put it into a petri dish and let it dry. Displays both the primary orthagonal cracks and the secondary polygonal forms after a couple of days. Pretty cool.
