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)

This is the fortress town of Shatili in an extremely remote Caucasus region in Georgia called Khevsureti. It was built by the Crusaders 1,000 years ago. The Khevsur people who live here trace their ancestry back to these Crusaders and until the 1930s still wore chain mail in feud-battles with other towns. I took this picture in 1991.

American traveler Richard Halliburton (1900–1939) saw and recorded the customs of the Khevsurs in 1935. The Khevsur men, dressed in chain mail and armed with broadswords, wore garments full of decoration made up of crosses and icons. They don’t do that anymore, but they proudly retain their Crusader Christian heritage – for Georgia adopted Christianity in the 4^th century AD.

This is one of the truly great mountain sights on earth yet never seen – except for professional mountaineers and those on our Himalaya Helicopter Expeditions. Kanchenjunga at 28,169 feet (8,586 meters) is the world’s 3^rd highest mountain (after Everest and K2), with a drop from summit (the peak on the left in front of the cloud) to the glacier at it base of 12,000 feet straight down.

You can be awed by such a picture, but to actually physically be here, to witness this magnificence personally so that it is forever a part of your life, is to feel a depth of awe that has to be experienced to be understood. Kanchenjunga is part of the Himalayas, now on the border of Nepal and Sikkim, once an independent kingdom now absorbed into India. We fly right up the North Face, and into the Amphitheatre of the Southwest Face as well.

We’ll be here once again next late October. (Glimpses of Our Breathtaking World #31 photo ©Jack Wheeler)

The best place to see Roman ruins is not in Rome or anywhere in Italy. It’s in Africa – specifically on the Mediterranean coast of Libya. This is the Roman theatre at Sabratha built in the 1^st century BC. Over 2,000 years old, it’s still mostly intact. Starting as a Berber village, the Phoenicians founded the city as Sabrat by 500 BC. Then came the Greeks, then the Carthaginians, and after the Punic Wars came Rome.

The Libyan coast was a lush fertile place back then. So much so that Sabratha and the other major Roman city nearby, Leptis Magna, produced several million pounds of olive oil per year – sale of which to Rome enabled them to achieve great wealth. It’s a shame that Libya remains today in chaotic civil war. Hopefully the day is not off when experiencing Rome’s most magnificent remains will be possible here again.

In the early 1600s, some 150,000 Armenians fled persecution from the Ottoman Empire to settle in Isfahan, Persia under the protection of Shah Abbas. There they created an extraordinary trading network that stretched from Amsterdam to Manila, becoming prosperous in the process. This enabled them to build extraordinary Armenian Apostolic Church cathedrals – Armenian Christianity being one of the oldest Christian denominations originating in the 1^st century AD.

Here you see the Armenian Apostolic Church in Isfahan, built in 1606 and dedicated to Saint Joseph of Arimathea, the disciple who took Jesus’ body off the Cross. The Armenian Quarter of Isfahan remains populated by thousands of Armenian Christians today who may freely practice their faith, albeit strictly within the confines of their neighborhood and never beyond. Nonetheless, it comes as a shock to see this in present-day Mullah Iran. (Glimpses of Our Breathtaking World #262 photo ©Jack Wheeler)

In a remote valley between the northern escarpment of the Tibetan Plateau and the Gobi Desert of Inner Mongolia, you find these magic painted mountains of red sandstone created by Himalayan uplift and millions of years of erosion. It’s at the sunrise light of early dawn that the colors are most apparent before they get sunwashed in the bright of day. It takes quite a hike in pre-dawn darkness to get to the right viewpoints at the right time, but certainly worth it. (Glimpses of Our Breathtaking World #261 photo ©Jack Wheeler)
