Remote granite walls offer some of the most exhilarating climbing experiences on the planet, but they also demand rock‑solid anchor skills when you're far from help. Mastering multi‑pitch anchor building on these sheer faces is a blend of geology awareness, precise technique, and disciplined safety habits. Below is a step‑by‑step guide to help you build reliable anchors that will keep you---and your partner---safe pitch after pitch.
Know Your Granite
Granite is a coarse‑grained igneous rock composed mainly of quartz, feldspar, and mica. Its key traits for anchoring are:
- High compressive strength -- can hold huge loads when the load is applied perpendicular to the bedding.
- Variable fracture patterns -- joints, exfoliation sheets, and mineral veins create both solid features and potential weak planes.
- Surface texture -- often slick when wet; dry granite offers excellent friction for cams and nuts.
Before you start placing gear, spend a few minutes scanning the wall for:
- Solid blocks or flakes that sit flush with the rock.
- Natural constrictions (narrow cracks, pockets, or flares) where passive gear can wedge securely.
- Avoid areas with visible spalling, loose flakes, or heavy vegetation that could hide rotten rock.
Core Principles of Anchor Building
- Redundancy -- Always use at least two independent placements. If one fails, the other should still hold the fall.
- Equalization -- Distribute the load evenly among all pieces so no single point is overloaded.
- Angle Management -- Keep the angle between anchor legs ≤ 60° (ideally 30‑45°) to avoid excessive force multiplication.
- Directionality -- Anticipate the direction of pull (usually downward and slightly outward) and orient placements accordingly.
- Simplicity -- Fewer components mean fewer failure points and quicker checks.
Gear Selection for Remote Granite
| Gear Type | Why It Works on Granite | Recommended Specs |
|---|---|---|
| Cams | Excellent in parallel-sided cracks; granite's smooth surface lets cams seat firmly. | 0.5‑3 in (double‑stem) with a wide range; consider micro‑cams for thin seams. |
| Nuts (Passive) | Granite often offers natural constrictions where nuts can bite. | Offset nuts (e.g., Wild Country Rocks) and standard wedges; carry a range from 6 mm to 25 mm. |
| Hexes | Useful in irregular or flared placements where cams might walk. | Medium to large hexes (10‑30 mm). |
| Slings & Cordellettes | For equalization and extending reach. | 12 mm nylon slings (60 cm) and 8 mm cordelette (≈ 5 m). |
| Carabiners | Locking for critical connections; lightweight for long approaches. | Auto‑locking gate (e.g., Petzl Attache) for master point; wiregate for secondary links. |
| Personal Anchor System (PAS) | Quick, adjustable tether to the anchor while you manage the rope. | 12 mm dyneema PAS with a built‑in carabiner. |
Step‑by‑Step Multi‑Pitch Anchor Building
4.1. Scout the Belay Ledges
- Look for a flat, spacious stance where you can stand comfortably and place gear without overreaching.
- Verify that the ledge itself is solid; tap lightly with a hammer to listen for hollow sounds.
4.2. Place the First Piece
- Choose the strongest, most bomber placement (often a cam in a parallel crack or a nut in a tight constriction).
- Seat it fully, give it a firm tug, and clip a locking carabiner directly to the piece.
4.3. Add the Second Piece
- Position the second piece approximately 30‑60 cm away from the first, aiming for a triangular geometry with the belayer's harness at the apex.
- Ensure the angle between the two legs (as seen from the harness) stays ≤ 60°.
