What to Pack for Riggs Lake, Graham
A well-packed bag handles most of what this area can throw at you.
What you bring to Riggs Lake matters. This list reflects the actual conditions you'll encounter.
Essential
-
Water (minimum 2L) — Water sources marked on maps may be seasonal or dry; carrying enough to complete your route prevents a dangerous shortfall.
-
Navigation (map/GPS/compass) — Getting lost is the leading cause of backcountry search-and-rescue calls; reliable navigation prevents the situation entirely.
-
Sun protection (sunglasses, sunscreen) — Prolonged sun exposure causes headaches, fatigue, and heat exhaustion that can cut a trip short or create a medical emergency.
-
First aid kit — Remote locations mean longer response times for help; a first aid kit bridges the gap between injury and professional care.
-
Extra food — High-energy snacks weigh little but provide crucial fuel if you need to bushwhack out or wait for conditions to improve.
-
Headlamp with extra batteries — Hands-free light is essential for navigating uneven terrain, setting up camp, or signaling for help at night.
-
Fire starter — Waterproof matches or a ferro rod weigh almost nothing and can be the difference between a cold night and a survivable one.
-
Emergency shelter (space blanket) — Wind and rain strip heat faster than most people realize; a compact emergency shelter blocks both.
-
Knife or multi-tool — A multi-tool handles problems you can't predict: jammed zippers, tangled line, first-aid tape cutting, or gear fixes on the trail.
-
Extra clothing layer — A lightweight fleece or puffy stuffs small but provides critical insulation if temperatures drop unexpectedly.
Wildlife Gear
-
Hiking buddy (avoid solo) — A companion can help with first aid, signaling, and decision-making if a wildlife encounter turns serious.
-
Noise maker — Group noise is especially important in dense brush or near berry patches where bears may be feeding and less alert.
-
Gaiters — Thick gaiters deflect fangs before they reach skin, buying critical time in areas with rattlesnakes or copperheads.
-
First-aid snakebite kit — Knowing how to immobilize a limb, mark swelling progression, and avoid harmful folk remedies can improve outcomes.
Terrain Gear
-
Wide-brim hat — At high elevation where UV is 10-12% stronger per 1,000 feet of gain, a hat provides constant passive protection.
-
Sunscreen SPF50+ — Sunburn isn't just discomfort — severe burns cause fluid loss, fatigue, and impaired thermoregulation that compound in remote settings.
-
Extra water (desert) — In arid heat, your body loses 1-2 liters per hour during exertion; running out of water in the desert is life-threatening.
-
Headlamp (extra) — Cave exploration, deep canyons, and dense forest canopy create darkness even during daylight hours.
-
Emergency bivy — Unlike a space blanket, a bivy fully encloses you, trapping more warmth and blocking wind from all directions.
-
PLB/satellite messenger — In remote wilderness with no cell coverage, a PLB is your only way to call for help during a serious injury or emergency.
-
SPF50 lip balm — High elevation, snow glare, and desert sun amplify UV exposure on exposed facial skin, especially lips.
-
Extra hydration — Dehydration at elevation worsens altitude sickness symptoms and impairs the judgment needed for safe route-finding.
-
Slow acclimatization advice — Spending a night at a moderate elevation before pushing higher gives your body time to produce more red blood cells.
Seasonal Gear
- Spring: Camera, Wildflower field guide
- Fall: Camera, Binoculars (foliage viewing)
- Winter: Microspikes/traction devices
