CLAUDE, TX -- A massive crack in the earth opened up last week in Claude, Texas and it's creating a stir among geologists.
Geologists said Tuesday the crack was a joint in the earth's crust. They believe the opening is the result of a weak point in the joint where one spot slips away from the other.
Some parts measure more than 30-feet deep and it drained what used to be a pond. Experts say earth cracks are common but the size of the crack in Claude is not.

Basalt pillars in the Black Canyon, Colorado...are basalt pillars not *supposed* to be found on the margins of continents?

Evolution in Your FaceLake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!
