Between 320 and 280 million years ago, what’s known as the Ancestral Rocky Mountains formed as what are now the continents of Africa and North America were merging together. Over time, leftover sedimentary rock eroded and a geologic event known as the Laramide Orogeny, which took place between 70 and 45 million years ago, created what we see as the Rocky Mountain range. Today’s Rocky Mountain range spans roughly 3,000 miles in length from northern Alberta Canada to New Mexico. The range juts across British Columbia, Alberta, Washington, Idaho, Montana, Wyoming, Utah, Colorado, and New Mexico. In Colorado, an 18-mile-long, 15-mile-wide segment of the Rocky Mountains separates Boulder County to the east and the Grand County to the west. Seven peaks, 55 lakes, 73,932 acres, and 133 miles of trails makes up this section of the Rockies, known as the Indian Peaks Wilderness.
I always book a window seat on the right side of the plane when flying from Denver to San Diego. With both of my parents in ailing health for a number of years, I frequently made the trip out west for a two- or three-day visit. And every time I flew—to sit next to my dad in his wheelchair or drive my mom to the beach for just a few steps in the sand on her deteriorating body—I’d stare out the window of the airplane at the mountains below and to the northwest of Denver International Airport.
The trails winding up and down snowcapped peaks. The lakes that sit just below cirques, their blue water framed by sandstone, limestone, and gray shale. The ridgeline that connects the mountains I’ve come to know well. I’d identify peaks and lakes I’d run to on weekend adventures, routes I wanted to tick off on my next outing.
At home in Boulder, Colorado, I stare at maps. The good, old-fashioned paper kind. I choose routes in the Indian Peaks with trailheads between 40 minutes and an hour’s drive from my house. I pick my runs based on summits and lakes, mostly lakes. Depending on my fitness level, my company, or simply my mood, these runs range between five miles and 18. With the terrain climbing hundreds to, sometimes, thousands of feet in elevation over rocky terrain and crossing creeks, I’m usually on the trail between two hours and a full day. I never start my watch and don’t care about the pace. I stop often to take photos, splash mountain water on my face, sometimes jump in a lake, pet my dog. I run with a pack large enough to carry the fluids and fuel I need—energy chews, nut butters, gels—a rain or windshell, sometimes thin gloves and a beanie, a lip balm, a simple first aid kit, and my phone for a camera. The pack is also small enough to not hinder my movement, not weigh me down.

I already feel heavy as I’m driving down the long, bumpy dirt road to the trailhead of a route I’d been craving on the flight home from this particular trip to San Diego. My mom’s Parkinson’s had been advancing quickly. My dad’s dementia had taken away his ability to communicate, and to stand. I had arranged with my husband, even before boarding the plane, that I needed to head to the mountains the weekend after returning home. He’d take the boys to their soccer games. I’d be home by 1 or 2.
I left early, sipping coffee, craving trees. In September, the aspen trees on this particular trail flutter in the breeze, often against the clear blue sky. I needed to hear the movement, see the contrasting gold and cerulean.
My yellow lab and I moved along the trail together, the sound of my breath syncing up with the jangle of her dog tags. Her tail wagged, my heart pulled down the trail and toward a lake I’d been to before—one that took my breath away with its beauty, its peace.
When we got there, I sat. I tore open a bag of energy chews. Stared at the light glistening off the water, splashed a good amount of it on my face. The dog swam. I exhaled.
