HIGH-ALTITUDE ALPINE WEATHER & ELEVATION GEAR
[ ] Hard Shell Parka
[ ] UV Polarized Eyewear
[ ] Altitude Electrolytes

Hard Shell Parka: look for a hood that fits over a hat, and zippers you can use with gloves on.
UV Polarized Eyewear: UV protection matters more than tint. Snow and rock reflect extra light.
Altitude Electrolytes: these are a hydration aid, not a cure for altitude illness.

Be off the high ground before storms. Afternoon storms and lightning are common in the mountains. Start early, check the forecast and head down at the first sign of building clouds. Why it matters: open alpine terrain gives you nowhere to shelter from lightning.
Know the signs of altitude illness and act on them. Stop, rest, drink water, and descend if symptoms persist. Do not go higher with symptoms.
Keep your warmth and your fuel. Add layers before you are cold, eat and drink on a schedule, and turn back at your planned time. See nps.gov for current safety advice.

High-altitude loadouts: Rocky Mountain pack rules

Weight feels heavier at elevation. Trim anything you do not need, and keep your heavy layers on top of your pack where you can reach them. For park-specific rules on gear, camping and permits in Rocky Mountain National Park, see nps.gov/romo. For general pack weight tips, see the Beginner checklist "Pack Base Weight & Critical Load Limits."

Acclimatization tips

Give your body time to adjust before you go high. Spend a night or two at a moderate elevation if you can, drink water, eat well and take it slow on day one. Learn the early signs of altitude illness, such as headache, nausea, dizziness and unusual tiredness. Do not ignore them. Rest, and if symptoms do not ease or get worse, descend. For current guidance, see cdc.gov (Travelers' Health, high altitude) and nps.gov. For deeper reading, the Wild Dirt blog post "The Complete High-Elevation Acclimatization Protocol" is planned at wilddirt.com/blog/national-parks/high-altitude-acclimatization. {{LINK_PRK_ACCLIMATIZATION_POST}}

Night-sky readiness

Dark skies are one of the best things about high places, and the temperature drops fast after dusk. Pack a warm layer, a red-light headlamp and a plan for walking back in the dark. This is the doorway into the 90-minute Wild Dirt Twilight Series. {{TWILIGHT_PAGE_URL}}

Trail closures, snow conditions, permit rules, camping limits and storm warnings vary by park and change quickly. Check current local rules and the day's conditions on the park page at nps.gov, or the Forest Service at fs.usda.gov.

Big views come with big weather. Pack right, start early and respect the sky. A Wild Dirt hat and a warm drink in a Wild Dirt bottle round out the kit.
