Prospecting for Iron in Alaska
July 2003
The solo prospector in his canvas field clothes and skin-thick skiff is still king of the rain forest in southeastern Alaska.

November 2001
I opened the front door of my house at 5:00 AM to find it raining hard and water standing in puddles all over the driveway. Just great! It hadn’t rained for 3 weeks, and on the morning we were leaving for a weekend dredging trip, the weather decided to change.
