For a winter adventure that’s equal parts unforgettable and challenging, it’s hard to beat a winter ascent of Mount Marcy in the Adirondack High Peaks. Checking in at an elevation of 5,344 feet, Mount Marcy is the highest peak in New York and offers commanding views of the surrounding mountains, lakes, and valleys in all directions. With over 3,000 feet of elevation gain and a round-trip distance of nearly 15 miles via the shortest route to the summit, Mount Marcy makes for a long and challenging hike any time of year, but especially in winter when the temperature drops, the wind howls, and the days are short. Along with possessing the necessary fitness and knowledge, having the proper gear is paramount to completing a winter summit bid not only successfully, but also safely. In addition to common essentials such as a winter hat, gloves/mittens, snowshoes, and waterproof (and possibly insulated) hiking boots, the following 10 gear items are critical for any winter climb of Marcy.

Traction: EMS Ice Talons

Proper traction in winter is absolutely essential, and it seems like every winter weekend an unprepared hiker in bare boots (or even tennis shoes) slips and gets hurt in the High Peaks. With the amount of snow and ice varying from week to week in the winter, as well as with elevation, it’s wise to be prepared for hiking in both deep powder and ice-coated rock slabs on any winter ascent of Marcy. Even when the trail leading to the final summit approach is covered in feet of fluffy snow, the exposed, wind-swept rock slabs that comprise the summit dome are often largely devoid of powdery snow and are instead coated in a thick layer of ice. Snowshoes are typically too clunky and don’t offer sufficient traction for such terrain, but this is where traction devices such as the EMS Ice Talons really shine. Lighter and much more user-friendly than classic crampons, the EMS Ice Talons will allow you to confidently and safely navigate the rime ice and crunchy snow that will almost certainly be encountered below Marcy’s summit.

Trekking Poles: Leki Makalu Lite Cor Tec

The use of trekking poles while hiking is largely a personal decision, but they can be especially handy on a winter ascent of Marcy. In addition to alleviating some lower body stress (especially on the knees while descending), trekking poles can provide critical stability on the exposed final summit push where the wind can be so strong it can throw off your balance and sometimes even knock you on your feet. For hiking in powdery snow, be sure to put some wider baskets at the end of the trekking poles. Similar in concept to snowshoes, broader winter baskets give trekking poles better flotation in deep snow.

Snow Goggles

Snow googles will serve two purposes on this hike. For one thing, they’ll keep your eyelids from freezing shut if the summit is windy (which it often is) and snow is blowing in the air. Secondly, most snow goggles also act as sunglasses to protect against snow blindness, which can occur when unprotected eyes are subjected to extended periods of bright sunshine reflecting off of white snow. While you might be able to get away with using typical sunglasses for eye protection on calm days, mountain weather is unpredictable and winds can whip up in an instant, making snow goggles a prudent accessory to toss in your pack for a winter climb of Marcy.

Wicking Base Layer: EMS Lightweight Synthetic Base Layer Tights and Crewneck Long Sleeve Shirt

Sweating too much while hiking in the winter is one sure-fire way to get into a dangerous, hypothermic situation. Dressing in layers is essential for regulating body temperature, and it all starts with the next-to-skin base layer. Choosing a base layer material that’s wicking and quick-drying is key, and the old adage “cotton kills” comes to mind here. Unlike cotton, which takes a long time to dry once it’s wet and will sap your body of heat, it’s best to utilize synthetic materials or merino wool when choosing a base layer. The EMS Lightweight Synthetic Base Layer tights and crewneck long sleeve, for example, are made of moisture-wicking and quick-drying 100% polyester, which will pull perspiration away from the body to better regulate body temperature and prevent a bone-chilling cold to set in, especially while stopping for a break.

Outdoor Research Skyward II Pants and Outdoor Research Interstellar Jacket

Being at the highest elevation in the state comes with some of the harshest weather in the Northeast. For protection against wind, precipitation, and trudging through deep snow, a breathable outer layer that’s wind and water-proof is key. Pants such as the Skyward II, and a jacket such as the Interstellar (both from Outdoor Research) help form a protective barrier between you and the harsh winter elements, especially when in the exposed alpine zone.

Gaiters: Outdoor Research Crocodile Gaiters

Wet, cold feet are likely the most common complaint among people new to winter hiking. In addition to hiking in sturdy and waterproof boots, gaiters are the best accessory to ensure that feet stay dry and toasty, and are worth their weight in gold on hikes through deep snow. Gaiters effectively cover boot tops and prevent snow from getting in, even when hiking through waist-deep snow. The Outdoor Research Crocodile gaiters are the classic, gold-standard gaiter for winter hiking, and come with a Gore-Tex membrane to ensure that the gaiters don’t wet-out even in slushy conditions.

Socks: EMS X-Static Sock Liners and Smartwool Women’s PhD Pro Medium Crew Socks

Continuing with the keeping feet warm and dry theme, choosing the right socks can be the difference between a safe and comfortable hike and a painful and dangerous slog. Just as the aforementioned base layers for your upper and lower body help manage sweat and regulate body temperature, use a thin pair of synthetic liner socks like the EMS X-Static Sock Liners help to pull perspiration away from the foot to prevent cold and clammy feet. Following up the liner sock with a mid-weight sock such as the Smartwool PhD Pro adds extra insulation without overheating.

Down Jacket: EMS Men’s Feather Pack Hooded Jacket

As previously mentioned, layering clothing is critical in winter. A warm yet lightweight insulated jacket should always be in your pack in winter, and will come in handy while stopping to take a snack break and for braving the exposed alpine zone on the final approach to Marcy’s summit. Down offers an optimal warmth-to-weight ratio, and modern down jackets such as the EMS Feather Pack Hooded Jacket now offer water-repellent down which retains its insulation value even in wet conditions.

Headlamp: Petzl Tikka

Short winter days coupled with a nearly 15 mile round-trip hike means that part of your hike will likely be spent in the dark. Packing a headlamp (and spare batteries) such as the Petzl Tikka will help keep the trail illuminated and you safe when it’s dark out.

Insulated Water Bottle: Camelbak Carry Cap 32 oz Insulated Stainless Steel Bottle

Staying properly hydrated is always important while hiking, but no matter how much water you carry, it won’t do you any good if it’s frozen. Boiling water before the hike and keeping water bottles inside your backpack is typically good enough to keep water from freezing on a day hike, but an insulated water bottle or thermos such as the Camelbak Carry Cap 32 oz Insulated Stainless Steel Bottle will eliminate any doubt that your beverage of choice will be in a liquid state when you need it.
