United States Geological Survey field researchers have needed to get creative over the years at getting their boats up-stream. While portaging and lining up boats is common practice, the activity is far more amusing when undertaken while wearing such lovely field hats.

Portaging is when a boat is pulled out of the river, unloaded, and carried by its former riders. This can be to get around a particularly nasty hazard, or to take an overland shortcut between sections of river.

Lining up is an alternative when the boat stays in the river and is towed up-stream by its riders hiking along the banks or wading through shallow water. Leading the boat upriver by lining up is a preferable technique when the stream slopes are too steep to haul the boat out, or to avoid a brief hazard like a set of short rapids.
