Physical Improvements Crater Lake National Park–1928
1. Road System: Total 67 miles, consisting of 4 miles pavement, 21 miles of oil macadam, and 42 miles of dirt road. The dirt roads are extremely difficult to maintain because the soil is light volcanic ash and pumice which displaces almost as readily as fluid.
2. Trails: 36 miles, of which 33 miles are widely scattered and are used as much for protection as by visitors. Three miles consisting of the trail down the crater wall to the lake and the trail to the summit of Garfield Peak are used by at least 30,000 people annually; they contain such elements of hazard that their safe maintenance consumes practically all of our inadequate trail allotment.
3. Telephone System: 46 miles of iron wire, grounded system. Within the park this line serves a total of 26 telephones placed in various administrative units; on the west boundary our line joins that of the Forest Service; to the south connects with the Klamath Telephone Co. ; and to the east with the Indian Service. This telephone system is a good one of its type but no longer suffices for the greatly increased use to which it is put by the public particularly, there are no telegraph lines extended into the park.
4. Public Buildings: Anna Spring: 1 superintendent’s house, 1 ranger station, 1 bunk house used as a residence, 1 warehouse, 1 barn, 2 modern toilets in adjacent campground, 2 small shacks. These are all frame structures.

Wine Glass: 1 combination bunk house, 1 decrepit storehouse about 12′ x 20′.
Devils Backbone: 1 combination bunk house; 1 old frame storehouse about 10′ x 16′.
