Just as the Rim Road was
reconstructed into Rim Drive, the approach routes to
Crater Lake have also been realigned in response to
higher traffic volumes, increased speeds, and changing
connections to the regional road network. The greatest
changes to approach roads came in the 1930s, as the BPR
and NPS collaborated on building Rim Drive, though
redesign of small segments in each of these routes has
continued to the present. Most changes have stemmed from
functional concerns like improving curvature and
lessening grade, rather than a concerted attempt to
provide stopping points and vistas to motorists. None of
the approaches could "present" the central attraction of
Crater Lake, but they sometimes supplied interesting
views of the steam canyons and hinterland.
Initial changes in alignment
of the Fort Klamath — Jacksonville wagon road through
the park took place under superintendent W.F. Arant, who
started the process by hiring a location survey in
October 1902. This led to crews building 2 miles of road
in Munson Valley the following year and improving
sections of the wagon road between Annie Spring and the
park's south entrance. Work continued on both roads in
1904 through the use of hired labor and teams. Crews
completed the road through Munson Valley to Rim Village
in August 1905, one that possessed a graded width of
roughly 8' and a maximum grade of 10 percent.
Arant successfully pitched the
need for a new road from Whitehorse Creek to Annie
Spring, so construction of this wagon route began once
road crews reached the rim. The road built from
Whitehorse included one section with a 10 percent grade
over the Cascade Divide, but it ultimately shortened the
distance formerly traveled on the wagon road of 1865 by
a half mile and eliminated two relatively steep grades.
Although completion of the Whitehorse — Annie Spring
segment made travel easier, Arant pointed to the need
for widening and straightening portions of the 1865 road
still in use so as to better accommodate automobiles. He
described that portion of the road between the west and
south entrances of the park as being "tracks little
wider than a wagon and one or two feet deep, and it is
very difficult for teams to pass." Arant reported on
park roads as being kept in the "best condition
possible" with only limited funds available for
improvements, though widening had been accomplished in
places. Generally, however, the trees and other
obstacles were situated too close to road margins to
permit a team to turn out of the narrow track. Dust made
travel over any of the roads disagreeable over the
greater portion of summer, but this could be overcome
through the use of road sprinklers.
