| Waterscreening operation at the Guadalupe Bay site. By gently spraying sediment through nested ¼-inch and 1/8-inch-mesh screens, thousands of small and fragile artifacts and animal bones were collected. On calm, warm days waterscreeners went merrily about the business, but windy, cold days were quite another story. The plastic sheets seen here were used to direct the returning water back into the barge canal without causing further bankline erosioin, as well as to reduce the amount of cold spray on lower limbs.
