Camp made, I began the last lap of my climb up the glacier. Along the way, below snowbanks, wild flowers grew head-high, but in the woods beside the game trails they were scarce and stunted. As I plodded slowly up the steep slope I heard loud reports, as though some one were setting off heavy blasts. They echoed and reëchoed among the cliffs. A roaring stream dashed frothily down the slope, rocks rolled past. I climbed a pinnacle overlooking the glacier and looked down upon it. The Parson was right. All the snow which ordinarily hid the icy surface was melted away. The glacial ice lay uncovered. Its surface was split by numberless yawning crevasses. Water drenched their sides. Every little while ice would break away, and then reports, similar to the ones I had heard on my way up, would nearly deafen me. I climbed gingerly down and edged out upon the glacier, testing each foothold. I peeped into the crevasses, and dropped stones or chunks of ice into them to sound their depths. I ventured into a shallow crack and followed it until it pinched beneath a wall of solid ice. Then I tried another, a larger one. Gaining a little courage by these explorations, I ventured yet farther and climbed down into one of the deeper crevasses. Water showered down upon me, from melting walls above. I crept on down until I was about fifty feet below the top of the glacier. I paused; before me gaped a dark cavern fenced off by heavy icicles as large as my body. I peered through this crystal lattice into the darkness beyond. From somewhere came the tinkle of water, I decided to investigate. A stream pouring into the crevasse from above, had washed down a stone. Using it for a sledge, I set to work to break into that barred vault. I shattered one of the glassy bars and crawled inside. A ghostly blue light filled the place. With lighted candle I moved away from the entrance, turned a corner and plunged into the blackest darkness I have ever experienced. The silence was eerie, frightening. Just then it was shattered by a muffled report, followed almost at once by another that seemed to rend my cavern walls asunder. Bits of ice dropped about me. I suddenly remembered a number of things I wanted to do outside, I turned and sought the guarded cavern of the ghastly light. I mistook the way and turned aside into a blind alley for a moment. I grew panicky--my flesh went clammy--but that momentary delay no doubt saved my life. As I reached the opening, there came a rending crash, a splintering of ice, and broken blocks came hurtling into the crevasse just outside my cavern door. An inrush of air snuffed out my candle.
