Have you ever heard of the Gilbertson twins? My guess is probably not, which is surprising given what these two have been up to for nearly 30 years. MIT graduates Eric and Matthew Gilbertson have made it their mission to summit and survey the highest mountain in every country on Earth. So far, they’ve successfully climbed 145 country highpoints, documenting their journeys with detailed trip reports and photos. Similar to previous guest Steph Abegg, Eric and Matthew’s attention to detail and the sheer amount of free information they’ve made available on their website is astonishing. I highly encourage you to check it out after this episode.

When I first heard about their objective, I was overwhelmed with questions. How do you condense 145 mountains across 145 countries into a single conversation? Each country is distinct, and climbing its highest mountain poses its own difficulties, whether they’re technical, logistical, or even political. To top it all off, Eric and Matthew aren’t just climbing these mountains—they’re carrying surveying equipment to the summits to verify elevations with accuracy down to the inch. Their work has already corrected outdated information about multiple country highpoints, establishing the true highest peaks for locals and peak-baggers alike to celebrate. It’s an incredible endeavor that blends adventure, science, and the pursuit of global exploration.

In Part I of our conversation, we dive into the origin story of the Gilbertson twins and their vision for climbing country highpoints. We then start to explore some of the standout objectives that illustrate their experience over the last 30 years. We’ll also touch on their meticulous surveying efforts, what it means to truly measure a mountain, and the surprising conflicts they’ve faced along the way— even some with Wikipedia. Finally, we’ll discuss their reflections on climate change and the transformations they’ve witnessed firsthand in some of the world’s most remote and stunning peaks.

So, without further delay, I bring you Part I of my conversation with Eric and Matthew Gilbertson.
