The mood for "The Sentinel" comes from a memory I have of an early evening walk I took in the town of Lodge Grass on the Crow Indian Reservation in Montana. It had just stopped raining. As the sun dropped below the rain clouds, it produced a golden sunset and a spectacular double rainbow. Look closely: both the brave and the earth itself wear a wolf headdress. Cementing their bond, and their responsibility to each other, is a glorious rainbow and its reflection - an image that brings "The Sentinel" full circle. - BD
