Abstract
It is the purpose of this Bulletin to provide a general
picture of the Rogue River and a more detailed
river log of the wild reach of the river. The emphasis
of the log is on the geology that the river canyon
exposes. The wild reach of the Rogue River is sufficiently
remote to have discouraged geologic reconnaissance
in past years. Indeed, the same may be said
of the Klamath Mountain Province in general. Recent
interest in fitting the Klamath Mountains into the
new global tectonic framework has brought about
fresh interest in the geologic problems in this region,
yet the difficulty of working in terrain as rugged and
remote as this section of the Rogue River Canyon
continues to discourage detailed geologic mapping.
Consequently, the user of the River Log included in
this Bulletin often will be told what kinds of rock he
is seeing at a given point along the river, but may
find that the origin of the rock is obscure or its age
uncertain. Much more geologic work must be done
in this region before these small pieces can be fitted
together.
The Bulletin attempts also to present the broad
geographic and historical setting of the river along
its course from the Cascade Mountains to the Pacific
Ocean. This is done largely in preliminary sections
preceding the River Log proper, though occasional
biologic and historical notes punctuate the geologic
observations that constitute most of the Log. It is
hoped that hikers and boat travelers alike may come
to understand the river better. Only in such understanding
will its preservation lie.
