The ridge shelf that connected the Needlehouse to Coldwork Bench was a natural geologic terrace, carved out of the mountain flank where a massive layer of hard blue pale limestone rested upon softer, dark-grey calcareous shale. The shale had weathered back over hundreds of years. That left a broad, flat ledge thirty paces wide, carpeted with low subalpine juniper and dry, pale-yellow lichen.
Kezra walked along that high terrace on the morning of Day eighty-five. She felt the difference that Quarter rank had made in her senses of the landscape.
It wasn’t a mystical vision. It was a sharpened, almost painful clarity of load-bearing understanding. Where she had once seen merely cliffs, scree slopes, and gullies, her mind now instinctively divided the mountain into sixty-four-pace blocks and two-hundred-and-fifty-six-pace prisms. She noticed every upright joint in the limestone cliffs above them, tracing the shear planes where freeze-thaw ice had wedged the blocks apart. She looked down into the lateral gorge and calculated the angle of repose of the talus fans with an eye as cold and accurate as a mason’s weighted drop-line.
The two-mile cross along the high ridge shelf was a silent study in mountain geography. Kezra walked with her eyes fixed on the rock strata beneath her boots, reading the deep-rock history of the Spine like an open ledger.
