John Hanning Speke questions about the height and extent of the lake could not be answered easily. Speke's eyes were still bothering him and he only saw a small part of the southern end of the lake and his view was blocked by islands in the lake so he could not judge the size of the lake well. However, Speke did estimate the elevation of Lake Victoria at 4000 feet by observing the temperature at which water boiled at that level. (This lake's being substantially higher than Lake Tanganyika did make it a more likely candidate for the source of the Nile.) From
Mount Speke peaks: Kiyanja, Duwoni and Ingomwimbi. The fact is that for the Bakonjo the high Rwenzori is the home of Kitasamba, the god who resides at the high altitudes and cannot be accessed. Early European explorers visited the region in the search for the source of the Nile. This mountain was named after John Speke. While he never climbed this peak, Speke mapped the source of the White Nile in 1862. All the mountain in this region are named after similar early explorers. When Duke of the Abruzzi climbed this summit, he climbed all the other peaks in the Rwenzori range.
