My first Everest expedition was in October, 1987. I took this photo climbing above the Rongbuk Monastery. The enormous North Face of Mount Everest is entirely in Tibet.  The summit at 8,848 meters/29,029 feet is in the jet stream with the plume flowing left along the Northeast Ridge, the climbing route of Mallory and Irvine in 1924.

On the back side of the ridge is the Kangshung Face, also in Tibet.  On the right side is the West Ridge, the border between Tibet and Nepal.  At the right time of year, the setting sun turns the whole North Face bright pink.  At any time of year on a clear day like this, you are witnessing one of the most magnificent sights our planet has to offer.

This Xikrin-Kayapo tribesman and his people live in the deepest heart of the Brazilian Amazon on tributaries of the Xingu River. You wonder what he would think of us as panic, fear, and madness engulfs our civilization. Having spent time in his village not long ago, I’m confident he would simply shake his head in bewilderment and say, “Please just let us live our lives in our forest, that’s all we want.”

True indigenous tribes who keep to their traditional way of life are so rare now in the Amazon or anywhere else where they once flourished. Each one is a precious living cultural heritage of humanity. It is such a privilege when they share their way of life with you. They deserve to have their wish granted, as my tribesman friend would express it. (Glimpses of Our Breathtaking World #4 photo ©Jack Wheeler)

10,000 years ago, the Sahara was green, with lakes, rivers, and such an abundance of animals it was a hunting paradise for people who lived here. You’ll find their petroglyphs carved on to rock outcroppings like this that my son Jackson and I found on a Trans-Sahara Expedition in 2003.

The Milankovitch astronomical cycles that drive Earth’s climate produced a West African monsoon that greened the Sahara back then. When the cycles shifted ending the monsoon, the Sahara turned dry desert as it remains today. Political cycles that permitted a peaceful crossing of the world’s greatest desert have also shifted, making this too dangerous now.

A Trans-Sahara Expedition is one of the world’s great adventures. Hopefully, one will be possible again in the not-too-distant future. (Glimpses of Our Breathtaking World #7 photo ©Jack Wheeler)

In a remote corner of the Pacific Ocean, off the island of Pohnpei in Micronesia lies one of the world’s great archaeological mysteries: the only ancient stone city built on a coral reef. No one knows who built it or how.

Micronesians say their ancestors called it Soun Nan-leng, The Reef of Heaven. Their name for it today is Nan Madol, the City of Ghosts.

On artificial islets connected by a series of canals are massive walls up to 25 feet high enclosing temples, tombs, ritual centers, and platforms for thatch homes – all made of giant columnar basalt stone. Eons ago, lava flows on Pohnpei cooled into vertical pillars. Over a thousand years ago, ancient Micronesians began hauling these basalt logs miles away to build this stone city. With an average weight of 5 tons, 10,000 pounds – and some up to 25 tons, 50,000 pounds each – how they did this remains unexplained. It lies deserted today, abandoned and lost for centuries.

Paddling a kayak through the canal maze of Nan Madol to clamber over these monumental stone complexes in solitary silence – for visitors are rarely here – leaves you in a state of unforgettable awe. (Glimpses of Our Breathtaking World #6 Photo ©Jack Wheeler)

There are places in our world so staggeringly beautiful you have to see them to believe they exist. Yet those people walking along the foot bridge can’t see what you’re looking at. That has to be in the air, hovering from high above in a helicopter. We live in a world of such beauty it really does take your breath away. And best of all, the beauty of the Grand Prismatic Spring is right here in America. (Glimpses of Our Breathtaking World #2 photo ©Jack Wheeler)

April 22, 1990.  This is my son Brandon, age six, happily atop a small pressure ridge of sea-ice at 90 North Latitude, the geographic North Pole.  I started leading expeditions to 90N in 1978.  This was my 12^th, and the best weather there we’d ever had.  A glorious day at the very top of our planet, and a glorious memory for both father and son.

If fortune favors you with the opportunity, have grand adventures with your children or grandchildren when they are young. They will treasure the memories so much they will someday tell their grandchildren about them.  Life is short, carpe diem. (Glimpses of Our Breathtaking World #104 photo ©Jack Wheeler)
