This is an elevation profile of equinoctial plants of the Andes Region, using the cutaway technique. Drafted by Alexander von Humboldt (1769 –1859), centered on Mount Chimborazo. It includes 2 tables showing the distribution of plants and geology in the area, including large numbers of plant families, genera, and species names corresponding to the vicinity of the equator in South America.
The tables also show data about altitude, appearance of electricity, changes in weight, blueness of the sky, animals, location of the snowline, the boiling point of water, and atmospheric pressure, temperature, humidity, and composition.
