Starting in Spain at thePrime Meridian and heading eastwards, the parallel 40° north passes through:
The parallel 40° north formed the boundary between theKansas andNebraska territories, as per theKansas–Nebraska Act of 1854. It remains the boundary between the modern states ofKansas andNebraska.
The parallel 40° north formed the original northern boundary of theBritishColony of Maryland. A subsequentroyal grant gave theColony of Pennsylvania land north of the 40th parallel but mistakenly assumed it would intersect theTwelve Mile Circle, which it does not. Pennsylvania's border was thus unclear and the colony pushed for a border far south of the 40th parallel. TheMason–Dixon Line was drawn between 1763 and 1767 as the compromise boundary between the overlapping claims of these two colonies.

The parallel 40° north passes through the cities ofPhiladelphia, Pennsylvania,Boulder, Colorado, andColumbus, Ohio; as well as northern suburbs ofIndianapolis, Indiana and the southern suburbs ofPittsburgh, Pennsylvania. The parallel goes directly through theJohn Glenn Columbus International Airport, with runway 10L-28R lying immediately north of the line, runway 10R-28L lying slightly south of it, and the line going through the northernmost edges of the terminal. It also passes through the main campus of TheOhio State University; specifically, it cuts directly across the Oval greenspace, between University Hall and the William Oxley Thompson Memorial Library.Ohio Stadium, one of thelargest stadiums in the world, barely misses the parallel 40° north (6 seconds or 185 metres (607 ft) above 40° north).
Baseline Road in Boulder, Colorado, traces the parallel 40° north.
Thistle, Utah, aghost town since 1983, is slightly (30 seconds or 956 metres (0.594 mi)) below 40° north.
