Like rumbling thunderclouds or far-off explosions, the muffled booms broke the silence as we reclined on a slope of pulverized lava beads in a small passage near the top of a volcano in East Africa, nearly two miles up into the night sky.Like rumbling thunderclouds or far-off explosions, the muffled booms broke the silence as we reclined on a slope of pulverized lava beads in a small passage near the top of a volcano in East Africa, nearly two miles up into the night sky.
It was 5 a.m., and for six hours we had been scaling the colossal, pyramid-shaped Ol Doinyo Lengai — through waist-high tufts of grass in powdery ash, through loose rock and tight crevices and finally over hardened lava flows so steep I had to climb on all fours. Now we were exhausted, resting inside a fissure with chalky white walls. At sunrise, we would clamber the remaining 15 minutes onto the rim of the crater.It was 5 a.m., and for six hours we had been scaling the colossal, pyramid-shaped Ol Doinyo Lengai — through waist-high tufts of grass in powdery ash, through loose rock and tight crevices and finally over hardened lava flows so steep I had to climb on all fours.

“That’s the volcano underground,” Dennis Laiza, our Maasai guide, said.
I was starting to understand what it actually meant to be atop an active volcano.
We were nearing the spectacular climax of our grueling and astonishing weeklong journey through the Crater Highlands of Tanzania. The region sprawls along the East African Rift, where, millions of years ago, separating tectonic plates allowed magma to rise, belching out over many millenniums a multitude of volcanoes, many of them now collapsed calderas or dormant peaks.
