One of the principal continuing activities in the park during Steel’s superintendency was that of road construction under the direction of the Corps of Engineers. By the end of his tenure as superintendent Steel was able to report:
About 47 miles of excellent dirt roads have been constructed in the park under the direction of the Secretary of War, which consist of 8 miles from the Klamath, or southern entrance, to park headquarters; 7 miles from the Medford, or western entrance, to the same point; 5 miles from park headquarters to the rim of the lake at Crater Lake Lodge; 6 miles from the Pinnacles, or eastern entrance, to the rim of the lake at Kerr Notch; and 22 miles from Cloud Cap, on the eastern side, to a point about 1-1/2 miles south of Llao Rock, to the west of the lake, thus leaving 12 miles to complete the circle of the lake, which latter it is hoped will be finished during the season of 1917, thus affording one of the most wildly beautiful automobile drives in the world. These roads have had ample time to settle and it is now proposed to pave them, which work should be completed in about three years.
Earlier in 1914 Steel had explained his views on paving the roads under construction:
I understand it is the intention of the War Department to commence surfacing as soon as climatic conditions will permit in the spring of 1915. This plan is questionable, for the reason that if this is done it will be impossible for many years to get anything better, whereas if surfacing is left for the present it will permit of an effort being made to secure from Congress money with which to construct paved roads.
The time has forever passed when macadam roads will satisfy the desires of a progressive community, and they are rapidly being changed for something very much better. Then why construct something that will be unsatisfactory from the very beginning? According to estimates of the War Department it will cost $20,000 per annum merely to sprinkle such roads. It is the part of wisdom to build roads of such a character as that this heavy burden will not have to be borne. I hope to make the Crater Lake National Park self-sustaining in a few years, but if this great burden is to be added that happy condition will be delayed indefinitely.
In addition to the road network Steel was proud of the Mount Scott Trail he had initiated in the park. In 1916 he noted that
a system of trails has been outlined that will appeal irresistibly to visitors who delight in wandering over the bluffs, through the forests, and into uncanny spots where goblins dance by night and shadows linger by day. Chief among these is one to be constructed to the summit of Mount Scott, on a grade that can subsequently be widened for automobile use. When this is done one can ride in comfort to a point nearly 3,000 feet above the waters of the lake and nearly 5,000 above the plains of eastern Oregon, over which the eye can wander, intoxicated with the glory of a view from the Columbia River region to the mountains of California.
