Northwest Indiana comprises Lake, Porter, LaPorte, Newton and Jasper counties in Indiana. This region neighbors Lake Michigan and is part of the Chicago metropolitan area. According to the 2010 Census, Northwest Indiana has a population of 819,537 and is the state's second largest urban area after the Indianapolis Metropolitan Area. It is also the home of the Indiana Dunes, parts of which have been preserved through conservation efforts. The town of Ogden Dunes houses the Hour Glass, a museum showcasing the ecological and conservation efforts of O. D. Frank.
The region's largest city is Hammond, followed closely by Gary. Other municipalities in Northwest Indiana include Chesterton, Crown Point, DeMotte, Dyer, East Chicago, Griffith, Highland, Hebron, Hobart, Kentland, Lake Station, La Porte, Merrillville, Michigan City, Munster, Portage, Rensselaer, Schererville, St. John, Cedar Lake, Valparaiso, and Winfield.

Overview
The counties of Jasper, Lake, LaPorte, Newton and Porter are included in the Chicago-Naperville-Michigan City Combined Statistical Area, the broadest of the census-derived Metropolitan definitions. Unlike the majority of Indiana, which operates on Eastern Standard Time, these counties are among six in Northern Indiana that are in the Central Time Zone (the other being Starke). This reflects their close economic integration in the Chicago metropolitan area.
Three counties — Lake, Porter and LaPorte — are served by the Northwestern Indiana Regional Planning Commission metropolitan planning organization. Northwest Indiana is the home of Marktown, Clayton Mark's planned worker community.
The urban areas of Lake County and the contiguous urbanized part of Porter County are sometimes referred to as "The Region," or colloquially, humorously, or even pejoratively, "Da Region."
Geography
The Lake Michigan shore is a major attraction. Indiana Dunes National Lakeshore, which stretches from Gary to Michigan City, is a well-preserved stretch of sand dunes, beaches, grasslands, and forests, as well as several historical homes and buildings.
The terrain of Northwest Indiana varies from very steep and rugged at the dunes, to rolling in the moraines, and to pancake flat in the river valleys. It was shaped by glacial activity and Lake Michigan. The main geographical features of Northwest Indiana include the Valparaiso Moraine, Tinley Moraine, Lake Border Moraine, Iroquois Moraine, Calumet Shoreline, Glenwood Shoreline, Tolleston shorelines, and the Kankakee Outwash Plain.
Chicago Lake Plain
The Chicago Lake Plain covers the relatively flat northern quarter of Northwest Indiana north of the moraines. Initially, the plain was flat, composed of glacio-lacustrine deposits. These formed under the waters of glacial Lake Michigan. The lake formed from the melting glaciers north of the Valparaiso Moraine. Eventually the lake overflowed a low spot on the moraine at the Chicago Outlet near the southwest suburbs. This lowered the lake level to current day Lake Michigan levels (Horsley, 1986). As the lake shrunk, it left a series of sand ridges where its ancient beaches were. Along the Lake Michigan shoreline, the prevailing winds have built a series of dune ridges, breaking up the original flat surface of the Lake Plain.
Wheaton Morainal Plain
South of the Chicago Lake Plain in the central parts of Lake and Porter County and northern LaPorte county is the hilly Wheaton Morainal Plain. The Wheaton Morainal Plain consist of the Valparaiso Moraine and Tinley Moraine, paralleling the Lake Michigan Shoreline. The plain consist of rolling Wisconsinan-age moraines. The Morainal Plain is clayey till, and sandy and loamy till, with areas of sand and gravel. Other deposits include lake clay, silt, and alluvium. Deposits are between 50 and 200 ft thick, with many southern areas have over 200 ft of till (Mades, 1987).
Kankakee Outwash Plain
The Kankakee Outwash Plain (southern Lake, Porter, and LaPorte counties) is a flat outwash plain formed by the melting glacier, which was stopped at the Valparaiso Moraine. (Mickelson and others, 1984). Deposits are predominantly sand and gravel, but also include alluvium and fill materials. Deposits average less than 200 ft thick; in the lowlands they can be less than 50 ft thick, while in the upland they can be more than 200 ft thick. Local elevation changes are less than 100 ft. and include many scattered sand dunes.
Bloomington Ridged Plain
The Bloomington Ridged Plain covers only the most southern part of Northwest Indiana in the valley of the Iroquois River in southern Newton and Jasper counties. This area consists of low and rolling hills, i.e., moraines like the Iroquois Moraine with less than 300 ft changes in elevation. The soils are loamy till, lake clay and silt. Unlike the northern half of Northwest Indiana, the Huron-Erie glacial lobe left these deposits in its northeastward retreat. Deposits are less than 200 ft thick, with some more than 400 feet thick.
