Not far from Elsamere and Lake Naivasha is Hell’s Gate National Park, named after a narrow chasm among striking red cliffs that was once a tributary to a prehistoric lake in the Great Rift Valley. We begin on foot, and after days of cloudy weather and a bit of rain, the morning is clear and glowing with light that is perfect for photography. Our feet kick up fine dust, the remains of ash from nearby Mt. Longonot, which is dormant. Chunks of obsidian are shiny beneath the dirt.
In the distance, steam spurts from the horizon accompanied by a loud hum that indicate the Olkaria Geothermal Station, the first of its kind in Africa, established in 1981 and operated by KenGen, the leading power company in Kenya. There’s a huge push underway in Kenya to use renewable energy, but even this comes at a price. The water needed to operate the plant came from Lake Naivasha until the company began to dig boreholes. All power, ultimately, comes at some price.
The natural geothermal energy heats up spring water, which seeps from crevices and cascades down in small waterfalls, smelling strongly of sulfur. We explore the canyon, learning new plants, insects and amphibians.
Hell’s Gate is a heaven for birds of prey. Munir tells us about Simon Thomsett’s attempt to reintroduce bearded vultures back to the park and shows us the remains of the hacking site. A pair of Verreaux’s eagles cruise together across the sky to the north, back to the south, over to the west, landing briefly on the ground at a ridgetop near their nest before heading off again, coasting on the wind. We see a lanner falcon, perched near its nest at the top of a sheer cliff.
We also learn how poorly designed watering holes can be fatal for birds of prey.
We climb in the Land Cruiser to head deeper into the canyon, pausing to have a tea break under the tree where famous raptor biologist Leslie Brown sat to study a colony of cliff-nesting Ruppell’s vultures. The cliff is covered with whitewash, but there are only so many ledges. There are vultures on nests and vultures flying on wide plank-like wings eight feet tip-to-tip. Munir has counted up to 60-70 birds at a time at this site. Teeku sets up his 600mm lens and we take turns getting close-ups of the birds from a great distance, then we climb up to the base of the cliffs, searching for prey remains and feathers and eggshell fragments. We also get a spectacular view, spotting giraffes, marred only by the billows of steam and noise rising from the KenGen plant.We discuss how a park that is only 60 square kilometers can be so rich in raptors and plains game but also at odds with surrounding agricultural, pastoral and horticulture pressure.
We then hike down into the chasm of the canyon itself.
The rockclimbers of the group (Chris, Brian and Drew), cannot contain themselves!
