hmmm, wondering if there will ever be a market for Colorado crawfish? Tired of waiting until the crawfish season in LA to get them.

Tom Winters:Not to cast a negative note on this, but since crawdads are bottom-scrounging little varmints like lobsters, you might want to get a few checked by your county extension agent to make sure they are not harboring any heavy metals from pollution. This is a problem in a lot of coastal areas from pollution so why should you guys up there in Rocky Mountain oyster-land have it any better?
LAJim:Since a lot of the west was mined there are places with vast mine tailings on the surface in the watershed. Heavy metals will leech into the water and head downstream. Even though the water looks clean, it could have lead or other contamination. A listing of cities in Colorado reads like the periodic table.
Gold miners in northern California used mercury, thousands of tons of mercury, to separate gold from ore. Most of that mercury is still there. There are some stream beds where you can dig a bucket of mud and separate out a pound of mercury.
