A. A General Map of North America Drawn from the Best Surveys. John Russell introduced an entirely new feature to the topography of North America with this map by showing a long range of Stony Mountains in the west. At the northern tip of the mountain range are Mountains with bright stones with the discoveries of Hearne and Mackenzie shown in the Arctic. A large lake occupies the space where the Great Salt Lake actually lies, and the headwaters of the Colorado, Rio Grande, and Missouri rivers appear in close proximity to each other. Juan de Fonca's Inlet appears in the general vicinity of Seattle and there is no Vancouver Island. The United States are confined east of the Mississippi where 15 states are identified. Maine is not named and is given a very squat shape. Russell's map was copied by Reid the following year and influenced several other mapmakers of the period.

B. A General Map of South America Drawn from the Best Surveys. Detailed map of South America and the lower portion of Central America. Shows mountains, rivers, lakes, towns and a few roads. The mythical Lake Parime is shown in Guiana, and a large area in the center of the map is labeled Amazonia. The southern part of present-day Argentina is labeled Patagonia. At the left, along the Equator, are the Galapagos Islands.
