After a horrendous Autumn of forest fires in Colorado, we’ve received well over a foot of snow in a series of storms, and it’s safe to say Winter has arrived. Hiking season is never truly over in the Rockies, but Colorado’s famed Fourteeners are now blanketed in snow, increasing the risk of any attempted ascent exponentially. But through the fire and ice, the Summer yielded ample opportunity for at least one enthusiast to check off more of her bucket list adventures.

Since leaving her home in Paraguay, mountaineer and hiking expert Clarissa Acevedo Santos has spent over a decade ascending Colorado and Hawai’i’s highest peaks. In addition to her excursions in the Ko’olau and Kahalawai ranges including Maui’s Haleakalā crater, she has summited well over half the 58 peaks in Colorado over 14,000 feet, making her the first from her country of record to do so.

She was invited on her first Fourteener years ago when friends took her up Quandary outside of Breckenridge, CO, at 14,271′ (4350 m).

“When I hiked that first mountain, it was hard, because I wasn’t used to gaining that much elevation. I didn’t really enjoy it so much because of how cold it was on the summit. Even though I made it to the top, I wasn’t really having fun with not feeling my lips and not feeling my fingers because it was really, really cold. I could barely smile, and we couldn’t even enjoy the summit because of how windy it was!

“After that hike, I didn’t hike for a while, and I got invited again to climb Mt. Elbert in 2012. It was actually much more enjoyable because it was with a big group of college kids from Summit and the weather was just perfect. We were able to summit it and enjoy the day and have lunch up there. So that’s what started to change my mind about hiking Fourteeners because I enjoyed my time up top. That’s when I realized it’s not always difficult to be up there. I think I got what all the hikers call ‘Peak Fever’. So after that is when I feel like I started going non-stop, and I met more friends that were into hiking, and researched more about the mountain before I go.

“I always go with people who knew more about it, so I started learning more with other friends and other hikers. And I started feeling actually great when I got higher. It was always harder to get started close to the beginning [of the trail], just to gain all that elevation. But then when I was getting close to the summit, I just got more energy. I just got more excited to be at the top. That’s the goal. It’s a great feeling.”

Clarissa has an app that she uses to record all her summits called Colorado 14ers that allows her to keep record of and upload photos from every Fourteener she’s hiked. She pulls it up as she recounts year after year of more and more summits, some she’s even done more than once.

There is a class system rating every trail by level of difficulty, Class 1 being the easiest and Class 4 being the most difficult. The most difficult peak Clarissa recounts climbing is Long’s Peak, as well as the most dangerous weather she’s climbed in.

“It was a little bit late to summit it. It was not a good idea. If the rocks got wet, it could be very dangerous. There were people turning around. We decided to wait on a ridge. There were three [of us], and one turned around. He wasn’t feeling good, he was getting tired, he wasn’t used to hiking that many hours.

“We decided to wait for the clouds to go away. After that we just kept going. It did not rain on us, thankfully.”

Clarissa has seen her share of altitude sickness as well. One of her frequent hiking companions repeatedly gets stomachaches and headaches everytime they hike, in spite of being an experienced hiker as well.

“I always ask [one of my friends in particular] if she wants to stop or if she wants something. She normally doesn’t eat before she starts a hike. No breakfast. But I also carry ginger candy … I learned that from other hikers telling me it can help settle your stomach a little bit. It’s everywhere, in all the stores. Now they’ve created gums. I’ve started chewing them on my hikes just in case. You never know. I’ve seen people who hike all the time, and they ate something that didn’t digest well, and they feel sick and get a little dizzy.

“I’ve never experienced any headaches on the way up. The only time I remember having a headache is when I ran out of water. I hiked Oxford and Belford in the Saguache range in the same day. My head hurt and it lasted for that night. Now I take a filter with me so I can fill my [Camelbak] bladder. And I also take electrolytes. And I’ve started hiking with poles more as well, just because you put alot of weight on your knees when you’re hiking down. It’s very smart to start using poles.”

When it comes to preparing such demanding ascents, Clarissa recommends spending some time at an intermediate altitude before hitting the trail, and staying well-hydrated. Caffeine and alcohol the night before doesn’t typically help.

“It doesn’t matter how fit you are … you can still get really sick. I’ve heard of people who get headaches for several days because [they’re] not used to [the elevation here].”

She also says it’s important that you start any hiking at all to build the strength in your lungs.

“It does hurt,” she says about the stress on your respiratory system. “I remember when I was hiking Quandary, my chest was so pressed, my heart was [beating] so fast, my stomach was feeling weird, like I had to pee or I had to do number two or something. It was such a difficult part of … gaining all that elevation.”

“You’ve gotta find a good pace for yourself. I see many of my friends going really fast ahead of me, then they’re very tired and they have a hard time getting to the top. I’ve waited for many people because they are struggling so much at the end. Take as many breaks as you think [you need]. Carry enough water!“

Clarissa keeps seeing a lot of hikers running out of water. “They just bring a tiny plastic bottle. That’s a huge mistake. And bring food, too. You will get hungry after a mountain. It’s so funny how many people are unprepared. If I’m hiking with newbies, I make sure they have everything, and they’re always thankful.”

When it comes to clothes and shoes, Clarissa recommends really good traction. She’s tried some more affordable brands, but says the durability is worth paying more for.

Don’t ever hike in new hiking shoes before you’ve broken them in. Good hiking socks also have more padding at the heels and toes and help prevent blisters. She also will double-up on socks, or even bring an extra pair to help mitigate possible cold.

“I reapply sunscreen on my hikes two to three times. Many times my nose will burn. I always carry sunglasses. You’re so close to the sun, you don’t realize. You don’t want to burn your eyes or your face. Even with the sunglasses, having a hat on top of it doesn’t hurt. Even in the Summer in the mountains, carry additional gloves or layers, because you don’t know what the weather could be. Temperature changes quick.

“I just recently purchased a nice puffy Northface that helped me. I will always have a thin layer underneath because you get hot and cold. You’re gaining elevation, you get hot, then you get cold in the middle …”

When it comes to navigation, Clarissa’s main resource is 14ers.com, which allows you to download offline maps, so you aren’t relying completely on having cell service.

“Even though I have hiked many of them, I want to be sure I’m going the right direction … I just love reading everything I can beforehand. I read about the class, how much exposure, how long it’s going to take, then I download the maps, look at the maps, what kind of road it’s going to be, if my car can make it up higher or if I have to hike longer.”

Clarissa has heard of other Paraguayans hiking around the world, but has never met another one on a Fourteener personally. But she does meet a lot of people from around the world on these ascents who ask if there are mountains in Paraguay. The highest is Cerro Peró at 2762′ (842 m) in this landlocked country known more for its rivers and the hydroelectricity they provide for Paraguay and its neighboring countries, including Brazil and Argentina.

Clarissa says she’s learning more and more each year about mountaineering and advocates learning as much as possible about each ascent before you go. The weather may be different every single time.

Bring the layers, whether you think you’ll need them or not. And leave no trace.

Thank you, Clarissa, for sharing your continuing legacy, and be safe up there!

Clarissa is his wife who is increasingly a much faster, more experienced mountaineer than he is, but he will occasionally feel ambitious enough to join her on a Fourteener, at the top of which they both enjoy a delicious cider, weather permitting.
