Disappointment Cleaver

Summit
Schematic — orient with the compass, not for navigation
Disappointment CleaverThe standard DC route from Camp Muir
Season: the DC is in prime shape mid-May through late September, when the guide services mark and maintain the route (fixed lines, wands, crevasse ladders). A spring window means fewer people but a less-established boot pack — navigation is the #1 SAR cause, so a GPS with topo + map & compass skills are non-negotiable.
Top hazards (NPS): navigation errors in low visibility, under-training / fatigue (most common reason for turning around), crevasse falls, and steep icy slopes. Most accidents come from climbing into forecastable bad weather.

Safety & RisksHow the DC and Emmons compare
Common to both routes
Crevasse falls — both are heavily glaciated. Rope up, keep rescue systems ready, probe unknown snow bridges.
Whiteout & navigation — the NPS's #1 cause of rescues on Rainier. GPS w/ topo + map & compass are essential.
Storms, cold & wind — most accidents come from climbing into forecastable bad weather. Set turnaround rules.
Altitude — 14k ft on a fast profile; watch for AMS, hydrate, pace.
Under-training / fatigue — the most common reason parties turn back, and a contributing factor in accidents.
Disappointment Cleaver
Rockfall on the Cleaver — loose rock rib, worse when warm or when crowds are above you.
Serac & icefall on the upper Ingraham — the route passes under hanging ice ("the bowling alley"). Move fast, go early, minimize exposure.
Crowding — chokepoints and teams "in over their heads" add hazard on busy weekends.
Marked, maintained boot pack (in season) lowers navigation risk.
Faster rescue — Camp Muir shelter, rangers, and heavy traffic mean help is close.
Emmons–Winthrop
Self-navigation — no wands or boot pack; higher whiteout / route-finding & descent risk.
Remote — fewer parties around and a slower rescue response.
Crevasses on the Inter Glacier & upper "Corridor," entirely self-managed.
Glissade accidents on the Inter Glacier descent are a known Emmons hazard — control your speed, watch for rocks.
Less rockfall & serac exposure than the DC cleaver.
Net: the DC trades higher objective hazard (rockfall, seracs, crowds) for a marked route and quick rescue; Emmons trades solitude and less rockfall for greater self-reliance and slower help. For a first unguided Rainier the DC's support net usually wins — but a strong, navigation-confident team can find Emmons the safer-feeling choice on a quiet, stable window.

Crevasse-rescue standard for a party of 3: each climber carries ≥2 small pulleys, 2 prussiks, several carabiners, and the team needs at least 2–3 snow pickets as anchors. Rangers can deny a permit for missing crucial gear — pickets are your key gap.
Training PlanBuild the engine for a 9,000 ft day
Under-training is the #1 reason parties turn around. You've got a long runway — build a deep aerobic base first, then specificity (weighted vert). Weekly template: 2× zone-2 cardio · 1× long hike w/ pack · 2× strength (legs/core) · 1× stairs/vert · 1 rest.
Phase 1 — Aerobic Base now → ~4 mo out
Goal: consistent aerobic engine. 3–4 zone-2 cardio sessions/week (run, bike, hike), general strength 2×/week, weekly hike building duration. Just show up, keep it easy, stay uninjured.
Phase 2 — Build ~4 → 2 mo out
Goal: add load & vertical. Weighted pack hikes building to 30–40 lb, dedicated stair/vert workouts (2,000–3,000 ft), longer weekend days, heavy leg strength (squats, step-ups, lunges).
Phase 3 — Peak ~8 → 3 wks out
Goal: mountain-specific. Big pack carries (40–50 lb, 3,000–4,000 ft vert), back-to-back long days, a warm-up volcano (Hood, Adams, or Baker) for altitude + systems, and hands-on crevasse-rescue & self-arrest practice with the team.
Phase 4 — Taper final 2 wks
Goal: arrive fresh. Cut volume ~50%, keep intensity light, rest the legs, dial gear, sleep, hydrate. Fitness is banked — don't cram.
