Amazon.com description: Product Description: Into the Desert is the third volume of Roll On, Columbia, Bill Gulick's epic novel of the history of the Columbia River and the Great Northwest.
Covering the desert sector of the river from Celilo Falls to Canada between 1873 and 1948, this final volume deals with the lives of Captain Lars Warren and his wife Daphne as they build a home at Wallula Gap downstream from the mouth of the Snake River.
With the coming of railroads, the nature of the Columbia as a free-flowing river changes as man attempts to control it by jetties at its tumultuous bar, by locks and canals at the cascades and Celilo Falls, and by dams providing power, navigation, irrigation, and flood control. These changes are not always welcomed by the Warren family, but they have chosen to live here, they must make the best of it.
The climax of the novel, the massive flood of 1948 gives the dam-builders the final argument they need to begin the era of engineering that eventually will bring the second largest watershed in the United States under man's control. By the time the process is completed fifty years later, the once free-flowing river will be impeded by 161 dams.
