Clusters of vertical columns in nearby

James Harvey DeVotie (1814–1891) was a Baptist minister in the American South. Born in Oneida County, New York, he was a pastor in South Carolina, Alabama and Georgia. He was a co-founder of Howard College in Marion, Alabama, later known as Samford University near Birmingham. He was a long-time trustee of Mercer University in Macon, Georgia. He served as a Confederate chaplain during the Civil War. After the war, he worked for the Southern Baptist Convention.

Gilbert Hill is a 200 ft (61 m) monolith column of black basalt rock at Andheri, in Mumbai, India. The rock has a sheer vertical face and was formed when molten lava was squeezed out of the Earth's clefts during the Mesozoic Era about 66 million years ago. During that era, molten lava had spread around most of the Indian states of Maharashtra, Gujarat and Madhya Pradesh, covering an area of 50,000 square kilometres (19,000 sq mi). The volcanic eruptions were also responsible for the destruction of plant and animal life during that era.\nAccording to experts, this rare geological phenomenon was the remnant of a ridge and had clusters of vertical columns in nearby Jogeshwari which were quarried off two decades ago. These vertical columns are similar to the Devils Tower National Monument in Wyoming, and the Devils Postpile National Monument in eastern California, USA. Gilbert Hill was declared a National Park in 1952 by the Central Government under the Forest Act. In 2007, after years of lobbying by geologists, the hill was declared a Grade II heritage structure by the Municipal Corporation of Greater Mumbai (MCGM), and all quarrying and other activities around the monument were prohibited. Over the period of time, Gilbert Hill has faced severe erosion problems too.
