This episode explores the Sierra crest — a landscape built by volcanic fire, shaped by glacial ice, and transformed every winter by storms that remake the terrain. We look closely at Castle Peak and Basin Peak, two volcanic summits whose geology explains the bowls, couloirs, and wind‑loaded faces that define the area today.
We follow the wildlife that moves through this terrain in summer and retreats when winter arrives. We visit Peter Grubb Hut, a small backcountry refuge built in memory and carried forward by generations of winter travelers. And we trace the history of the transcontinental railroad, including the brief moment when Castle Peak was renamed for Leland Stanford before reverting to the name that actually fit the mountain.
The episode then turns to February 2026, when a persistent weak layer, a thin crust, heavy storm loading, and high winds created unstable conditions on the north‑facing slopes near Castle Peak. A fatal avalanche occurred on February 17th. We present this event factually and respectfully, acknowledging its place in the long story of the Sierra crest.
This is an episode about terrain, winter, and consequence — and about the understanding we earn when we move through mountains shaped by forces far older than us.

Two Sierra peaks sit side by side above Hope Valley — one flexible, one rigid — and together they wrote the contract that shaped the Pony Express, the valley below, and every traveler who ever tried to cross their terms.
Hawkins Peak and Pickett Peak look like neighbors, but they behave like opposites. Hawkins is the mountain that yields — a volcanic dome that lets storms roll over it and travelers slip around its shoulders. Pickett is the mountain that refuses — a stone throat that blocks weather, riders, and anyone who tries to force a passage through its narrow, unforgiving gap.
In this episode, we explore how these two peaks created the unwritten contract of Hope Valley. We dive into the geology that made Hawkins flexible and Pickett rigid, the human stories that unfolded in their shadow, and the night Boston Upson rode into a Sierra blizzard and accidentally proved which mountain the Pony Express could trust — and which one it couldn’t.
This is the story of two peaks with two personalities, and the terms they set for everyone who crossed their domain.

Some mountains are beautiful. Some mountains are dramatic. And some — very few — look like they were sculpted, not formed. The Nipple, a volcanic plug rising above Blue Lakes in the high Sierra, is one of the strangest and most irresistible landforms in California.
In this episode, we explore why this peak has such presence. We dive into the Miocene volcanism that built it, the Pleistocene glacier that carved the basin beneath it, and the rare alpine plants that cling to its volcanic slopes. We trace the human stories of the Blue Lakes basin — Washoe summer camps, Basque sheepherders carving their loneliness into aspen bark, and the early engineers who dammed the lakes and quietly tied this remote wilderness into California’s water system.
Blue Lakes becomes the stage; The Nipple becomes the sculpture. Fire built the mountain, ice revealed it, and solitude shaped the people who lived and worked beneath it.
Then we climb it — from the engineered shoreline to the barren volcanic crown — to understand why this improbable peak might just be the sexiest mountain in America.

Peakbagging is the simple, ridiculous, addictive act of turning red dots on a map into green ones — picking a list of summits, climbing every single one of them, and watching your app slowly transform from “you haven’t done anything” to “you’re becoming a menace.” It’s hiking with a scoreboard, walking with homework, and collecting mountains like they’re Pokémon. If there’s a dot, you climb it. If it’s red, you fix it.
In this episode, we dive into the strange, brilliant world of peakbagging — the mindset, the culture, the psychology, and the quiet madness of people who build their lives around touching summits. Peakbagging isn’t just climbing mountains; it’s a way of thinking, a way of moving through the world, a personal mythology written in contour lines and quiet ridgelines.
To bring it to life, I share a full, lived‑in story from my own attempt to climb twelve peaks in a single push — starting at Haskell Peak and following Route 89 all the way down toward the shores of Lake Tahoe. It’s a day that shows exactly what peakbagging really is: the diversity of terrain, the unexpected difficulty, the off‑trail scrambles, the private‑property puzzles, the moments of doubt, and the strange joy of watching the skyline change as you move through it. It’s a journey that proves peakbagging isn’t about one big summit — it’s about the rhythm of many.
We explore how the culture formed, why lists matter, how apps like Peakbagger quietly shape the modern experience, and what counts — and doesn’t count — as a “real” peak. We talk about the psychology of completion, the tribes within the community, the debates over prominence, and the shadow side of the sport: burnout, obsession, off‑trail hazards, and the responsibility of moving through land that isn’t always yours.
Whether you’re a seasoned peakbagger or someone who’s just starting to feel the pull of the skyline, this episode offers a deep, honest look at what it means to build a version of yourself that exists in high places.

In this episode, Philip kicks things off with a surprisingly heated argument — not with a person, but with AI — about the actual odds of running into a grizzly on his upcoming Penguin Peak hike in Alaska.
It’s a light, funny setup that leads into a deeper conversation about mountain safety, decision‑making, and why hikers worry about the things AI says they shouldn’t. While the purpose was to assess the risk of encountering a bear on a specific trail, the AI generates an overwhelming amount of facts on bears nd bear behviour, delivering a master class in mostly true information about the risks and dangers.

A weekend where I learned how to save lives using duct tape, optimism, and whatever was in my backpack — two days of practising CPR on a plastic torso that looked disappointed in me, splinting strangers who were pretending to be dead with Oscar‑level commitment, and discovering that every item I carry on a hike is apparently a potential tourniquet. It’s the story of how I became wilderness‑certified, emotionally unprepared, and now officially the friend everyone expects to rescue them when they fall over a rock.
A few weeks ago, Philip headed to Coloma, California to complete the Sierra Rescue Wilderness First Aid course — and it changed how he thinks about the outdoors. Not because he’s suddenly a backcountry medic, but because he finally understands how little you need to know to make a massive difference when things go wrong.
In this episode of Off You Pop, Philip shares what the weekend felt like: the chaos of the first scenario, the calm of learning a structured assessment, the comedy of improvised splints, and the surprising emotional shift that comes from becoming “the adult in the room.” This isn’t a tutorial or a medical lesson — it’s a nudge. A friendly shove to encourage anyone who hikes, climbs, camps, paddles, or wanders beyond cell service to take a Wilderness First Aid course themselves.
Expect stories from Coloma, reflections on upcoming adventures like Mt. Fuji and the Black Sheep Circuit, and a simple message at the heart of it all: competence is a kind of kindness.
If you love the outdoors, this one’s for you. Off you pop.

On this episode of Off You Pop, Philip sits down with Alison Hardy — CrossFit coach and mountain athlete — to unpack her attempt at the Tahoe Five Peaks Challenge. Alison made it through four summits and deep into the final push toward Genoa Peak before extreme winds and accumulated fatigue forced her to stop just short of the finish.
If you train for CrossFit, you already know what hard feels like. But today’s episode is about a different kind of hard — the kind that doesn’t end in 12 minutes, or 5 rounds, or when the clock beeps. It’s about a challenge that keeps stacking fatigue hour after hour until your brain becomes the real workout.
This is the story of Alison Hope’s Tahoe Five Peaks attempt — four summits down, deep into the fifth, and a day where wind, exhaustion, and decision‑making under pressure pushed her right to the edge. Not impossible. Just not not impossible.
And that’s exactly why it matters.
Because what Alison did out there is the same thing you train for in the gym: mental resiliency, composure under stress, and the ability to keep moving when your body is done negotiating. This episode is about what happens when a CrossFit mindset meets a 24‑hour mountain challenge — and what you can learn from it.
She walks us through the physical and mental demands of the T5, the decisions she had to make under pressure, and how endurance challenges translate directly into the mental resiliency she trains with her athletes every day. This conversation explores what it means to test your limits, how to respond when conditions turn against you, and why “doing hard things” matters inside and outside the gym.
Alison completed 49 miles, more than 11,500ft in elevation gain, completing Mt Rose, Granite Chief, Tallac, Freel and nearly Genoa in under 24 hours before finally reaching her limit.

A three‑summit volcanic spine that moves like a quiet procession across the Sweetwaters, where East, Middle, and South Sister rise in sequence like sentinels of an old Nevada kingdom. It’s a traverse built from wind, solitude, and long ridgelines that feel ceremonial — a mountain line that doesn’t test you with brutality, but with the kind of silence that asks who you are when the world falls away and it’s just you.
In this episode, we take on the Sisters of the Sweetwater Range (East Sister, Middle Sister and South Sister)— a volcanic trio rising above the Nevada–California line with more solitude than signage and more character than most people expect from this corner of the Great Basin. What was supposed to be a clean traverse turned into something far better: an off‑trail, north‑side ascent that forced us into the raw texture of the range.
I was out there with my friend Ben, who joins me on the show to talk through the day. We ended up climbing a line almost no one uses — a direct push from the north that pulled us through steep ribs, loose volcanic rubble, and the thick, red‑green manzanita belts that define the Sweetwaters. Those manzanitas are no joke: waist‑high, interlocked, and stubborn, the kind of brush that makes you earn every foot of elevation. They’re also part of the mountain’s personality, the thing that tells you you’re not on a trail, you’re in the Sweetwaters proper.
This is the story of the geology and the history of the mountains and of a route that didn’t go the way we planned — and ended up being better for it.

A 12‑day loop around Lake Tahoe becomes a full‑body story as Dom walks us through the long ridgelines, the granite mornings, the mental resets, and the unexpected freedom of naked hiking — a conversation about what happens when you strip the trail down to its essentials and let the landscape decide who you are by the time you finish the circle.
Twelve days. One massive loop. A trail that circles an entire lake and quietly reshapes the person who walks it. In this episode of Off You Pop, Dom joins Philip to unpack his full 170‑mile journey around the Tahoe Rim Trail — the highs, the lows, the granite, the grit, and the unexpected moments that made the experience unforgettable.
Dom takes us day by day through the rhythm of long‑distance hiking: the early starts, the mental resets, the tough climbs, the trail magic, and the quiet revelations that only arrive when you’ve been walking for a very long time. It’s not just a recap — it’s a look at what happens when you commit to something big and let the trail do its work.
If you’ve ever wondered what a multi‑day effort really feels like, or you’re dreaming of tackling the TRT yourself, this episode gives you the insight, the honesty, and the inspiration you need.
Off You Pop — let’s walk the long way around.

A debate that starts with two hikers and ends with a full‑blown philosophy of movement — one side arguing that poles are the secret to efficiency and saved knees, the other insisting they’re nothing but clacking crutches that ruin rhythm, clutter the trail, and turn humans into four‑legged metronomes.
Philip and Jason take on one of the most divisive questions in the mountains: should hikers use trekking poles, or should they be banished to the same dusty corner as zip‑off pants and bear bells? Philip comes in hot on the anti‑pole side — arguing that poles ruin rhythm, clutter the trail, and turn perfectly good hikers into four‑legged metronomes. Jason fires back with the pro‑pole gospel: efficiency, stability, saved knees, and the smug satisfaction of clicking your way up a climb like a Nordic superhero.
What starts as a gear debate turns into a full‑blown philosophy of movement — how we climb, how we descend, how we carry ourselves through the backcountry, and why the tools we choose say more about us than we think. It’s sharp, funny, occasionally unhinged, and surprisingly heartfelt.
Death to Hiking Poles is Off You Pop at its best: two friends on opposite sides of a ridge, arguing their way toward a deeper truth about hiking, identity, and the strange little habits that make us who we are.
