I am trying to locate a mountain 15-20 miles north of lake Kivu, which was named mount sharp by an explorer Grogan in about 1890. He wrote a book called "from Cape to Cairo" with his companion Arthur Sharp naming the mountain after him. Sharp is my great grandfather and my brother and I want to determine whether it can be safely climbed. Grogan describes six volcanoes north of Lake Kivu and this as being in a western section of two mountains, the other being higher. it as a mountain that has a crater several miles in circumference.
Can you help me by identifying the modern name of the mountain, how I can obtain a map of the area and how we could climb it if this is safe?
