Days and weeks of rare pleasure may be had in the exploration of these amazing walls, a pleasure greatly to be enhanced by discovering and studying the many plain evidences of Mazama's slow upbuilding and sudden extinction. The excellent automobile road around the rim affords easy approach afoot as well as by automobile and bicycle. Its passage is enlivened by many inspiring views of the outlying Cascades with their great forests of yellow pine and their lesser volcanic cones, some of which, within and without the park boundaries, hung upon the flanks of Mount Mazama while it was belching flame and ash, while others, easing the checked pressure following the great catastrophe, were formed anew or enlarged from older vents. From this road any part of the fantastic rim may be reached and explored, often to the water's edge, by adventurous climbers. What more enjoyable day's outing, for instance, than the exploration of the splendid pile of pentagonal basaltic columns suspended half-way in the rim at one point of picturesque beauty? What more inspiring than the climbing of Dutton Cliff, or, for experienced climbers, of many of the striking lava spires? The only drawback to these days of happy wandering along this sculptured and painted rim is the necessity of carrying drinking-water from the Lodge. Then there are days of pleasure on the water. Wizard Island may be thoroughly explored, with luncheon under its trees by the lakeside. The Phantom Ship's gnarled lavas may be examined and climbed. Everywhere the steep rocky shore invites more intimate acquaintance; its caves may be entered, some afoot, at least one afloat. The lake is well stocked with rainbow trout, some of them descendants of the youngsters which Will G. Steel laboriously carried across country from Gordon's Ranch, forty-nine miles away, in 1888. They are caught with the fly from shore and boat. A pound trout in Crater Lake is a small trout. Occasionally a monster of eight or ten pounds is carried up the trail to the Lodge. During all these days and weeks of pleasure and study, the vision of ancient Mount Mazama and its terrible end grows more and more in the enlightened imagination. There is much in the conformation of the base to justify a rather definite picture of this lost brother of Hood, Shasta, St. Helens, and Rainier. At the climax of his career, Mazama probably rose sixteen thousand feet above the sea, which means ten thousand feet above the level of the present lake. We are justified too in imagining his end a cataclysm. Volcanic upbuildings are often spasmodic and slow, a series of impulses separated by centuries of quiescence, but their climaxes often are sudden and excessively violent. It seems more probable that Mazama collapsed during violent eruption. Perhaps like a stroke of lightning at the moment of triumph, death came at the supreme climax of his career.
