<div style='text-align:Left;'><div><div><p><span>This feature layer depicts townships and sections (Public Land Survey System - PLSS) within the State of Alaska. This information was compiled by, and is maintained by the Bureau of Land Management, Alaska State Office, Anchorage, Alaska.</span></p><p><span>The Public Land Survey System is a grid-based land survey system that divides land into 36-square-mile townships. Each township is 6 miles east/west and 6 miles north/south. Townships are referenced to a paricular meridian which provides the basis for the numbering system. Although the term <span style='font-style:italic;'>township </span>is used generically when referring to a 36-square-mile block, there are actually three designators that fully describe a block. Townships are numbered north/south, while ranges are numbered east/west. The meridian is also needed for a complete description For example, <span style='font-style:italic;'>Township 8 North, Range 71 West, Seward Meridian</span> identifies a 36-square-mile block that is 8 townships north of the Seward baseline and 71 ranges west of the Seward principal meridian.<br /></span></p><p><span>Each township is further subdivided into sections, which are one square mile in area, and are numbered sequentially from 1 to 36, starting in the northeast corner of the township and proceeding in an alternating west/east and east/west direction to Section 36 in the southeast corner of the township. Below is a diagram that depicts the PLSS;</span></p><div style='text-align:center;'><figure><div><img height='432' src='https://miro.medium.com/max/716/1*F0n_3fkRyaasN2-2BiVjhg.png' width='358' /></div></figure></div><p><span></span></p></div></div></div>
