Deep Impact extends the legendary Halley’s Comet, carving through Squamish’s Dog Wall with seven sustained pitches of splitter crack climbing. This route demands commitment and finesse, threading long finger and hand cracks that invite both quiet concentration and bursts of dynamic movement. From the moment you set off on the first pitch’s exposed traverse to the final graceful pull on a right-angling finger crack, the climb blends technical precision with atmospheric wilderness. The rock feels alive here — the flaking edges beckon careful footwork, while the forested ledges provide moments to breathe deep and exchange knowing smiles. The route’s sustained nature and protected line encourage a patient rhythm; gear placements are plentiful but require attention, especially where offset cams become essential for maintaining security.

Located on the quieter expanse of Dog Wall, Deep Impact offers an escape from Squamish’s busier corridors. The approach meanders through mixed forest paths toward a granite slab known for its clean cracks and impressive exposure. Each pitch reveals a distinct character: a delicate slab traverse on pitch three, a golden corner cracking open on pitch four, and the demanding flared cracks on pitches five and six that test both technique and mental resolve. The sequence of moves flows from precise face climbing to sustained crack jams, culminating on a forested ledge where hands can finally loosen and eyes take in sweeping views.

Expect to spend the day navigating well-protected terrain that ranges from moderate 5.7 moves to harder 5.11a challenges. The crack systems reward those prepared with a strong crack climbing toolkit and patience to find solid placements amidst corners and crack widths that vary from thin fingers to off-widths. Descending demands equal care: eight to nine rappels weave down through ledges and forest terraces, with clear chain anchors marking the way. Returning can be as engaging as the ascent, inviting climbers to savor the alpine quiet before returning to Squamish’s lively base.

This climb is ideal in spring through early fall, avoiding wet or icy conditions that make granite slabs slippery and risky. Early starts help to stay ahead of afternoon winds and possible clouds, letting climbers enjoy the sunlit cracks and cooler forested rests. Footwear with good edging and crack-specific gloves enhance comfort, while plenty of water and layered clothing prepare for the variable mountain climate.

Deep Impact is not just a test of skill but a passage through one of British Columbia’s premier climbing areas. The route's historical roots run deep, with first ascents spanning decades — a testament to its lasting appeal and evolving mastery. This is a climb that satisfies both the technical climber hungry for quality crack lines and the adventurer eager to absorb Squamish’s raw natural beauty without crowds. Whether linking pitches or belaying on broad ledges shaded by cedars, the experience combines technical challenge with textured wilderness, offering a full day of climbing that lingers well after the last rappel.
