What is the theme in For Jennifer, 6, on The Teton by Richard Hugo?

Nature is a theme in the book. Nature has long been a source of inspiration to poets and writers, many of them finding in it meaning and purpose. By setting his poem on the Teton River, Hugo demonstrates his connection to and respect for the natural world, and by using the river as his central symbolic image, he pays tribute to the tradition of poets and thinkers who have similarly found in rivers insight into the human condition and lessons for living.
