K- Starting in SW Colorado in the San Juan Mountains then flowing south through the middle of New Mexico, past Albuquerque, then coursing generally southeast as the border between Texas and Mexico, making a big bend, and then emptying into the Gulf of Mexico at Brownsville, Texas, and Matamoros, Mexico. The mouth of the river is located at the gulf of mexico; Cameron county, Texas, and Matamoros municipality, Tamaulipas. The Rio Grande is 1,885 miles (3,034 km) long, is the fourth longest river system in the United States.
M- the countries around the Rio Grande are: Colorado, New Mexico, Texas, and Mexico.

This is a map or the cities around the Rio Grande.
Albuquerque NM
There are some plats such as algae, bulrushes, duckweed, milfoil, sedges, stonewort and cattail that grow around the river. Some of these plants that grow here make food that feed animals like amphibians, beavers, muskrats and a lot of different kinds of song birds. The Rio Grande moves slowly through Albuquerque. In Albuquerque there are irrigation canals and drains that go through the valley. The irrigation canals don't always have water in them, from march till October but the drain system has water all the time.
Ciudad Juárez Mexico /El Paso TX
Ciudad Juárez is one of Mexico's biggest citys. People who live in El Paso cross the river (the border) to visit. Between these two cities is where the start of where the Rio Grande splits the U.S. from Mexico all the way down to the Gulf of Mexico. this is one of the main international borders between the U.S. and Mexico along the Rio Grande.
Nuevo Laredo Mexico/ Laredo TX/Brownsville TX/ Matamoros Mexico
These two cities are also one of the major international borders between the U.S. and Mexico along the Rio Grande. People illegally go into the U.S. to Brownsville TX from the city of Matamoros in Mexico and also the other way too. where these two cities are people can just walk right across the river. They want to make that part of the river wider and deeper so that the problem with having illegal immigration there will stop. Mexico wants to stop the immigration by putting a fence up but Texas doesn't want to because it would cut off some of the farmers water sources. The Brownsville major doesn't want to widen or deepen the river because it would cost a lot of money.
N-The Late Cenozoic geology of the Rio Grande rift in north-central New Mexico chiefly reflects the competing contributions of fluvial/colluvial sedimentation and fluvial erosion, both of which were strongly influenced by climate change during the last 5 million years. A new compilation of the 1:100,000-scale Albuquerque map sheet shows that major features of the regional landscape are recorded by the Pliocene and Quaternary geologic units. The underlying Miocene section is variably tilted and only exposed on the rift margins; it was deposited during the most active period of rifting in closed tectonic basins by low-energy stream systems. Much intra-rift deformation, including local uplift and arching, pre-dates an erosional unconformity that marks the base of the Pliocene Series. The broad mesa west of the Rio Grande and gravel-capped pediments around the Ortiz and Jemez Mountains mark the constructional tops of coarse Pliocene beds that were deposited by higher-energy streams as a result of wetter, cooler climate than existed earlier. Closed-basin conditions persisted until Late Pliocene, marked by floods of basalt lava (2.7 to 2.5 Ma) that generally cap the Pliocene fluvial deposits. Capture of the Albuquerque valley drainage southward in Late Pliocene initiated the first through-flowing trunk stream ("ancestral" Rio Grande with its tributaries: Rio Puerco, Rio Jemez, and Galisteo Creek) and led to considerable erosion of rift-fill deposits and the surrounding mountains. Early Pleistocene initiation of the glacial-pluvial climate cycle is recorded by 1.6 to 1.2 Ma fluvial terrace-fill deposits east of the modern valley. Three additional inset terrace-fill deposits along the Rio Grande date from corresponding glacial intervals at about 640 ka, 150 ka, and 25 to 15 ka. East of the rift in the Estancia Basin, we recognize previously unreported shoreline deposits of a Pleistocene lake (probably ca. 150 ka).W-

Cultural:
M- Rio Grande is spanish for Big River but it is also called Rio Bravo which means rough river in spanish. Before the people who live near the river were there, there was Indians that lived there. When the Europeans started to move out west the indians that lived there would move more west closer to the Rio Grande.
Some of the indian tribes that used to live near the Rio Grande:
Concho, Karankawa, and Tonkawa indians:They ate fish from the Rio Grande.

K-The national conservation group American Rivers ranked the Rio Grande as the seventh most endangered river in the United States. The Rio Grande is already being polluted with raw sewage everyday but now contains toxic chemicals. The city's health director has banned swimming in part of the river due to a death of a thirteen year old boy. The chemicals in the river has caused a seriouse brain infection.
That great icon of the old west, the Rio Grande River, is drying up. At best, a bare trickle of river water is all that reaches its natural terminus, the Gulf of Mexico. Further upstream, slower, shallower flow is concentrating pollutants and endangering wildlife, including humans. The causes include a long-term drought, wasteful water practices by agriculture, and poor management of available water.
