geography

In addition to the independent city of Denver, Arapahoe borders on the Counties of Adams (as well as Denver until 1902 still under the administration of Arapahoe), Washington , Lincoln , Elbert and Jefferson . The district boundaries between Arapahoe, Denver and Jefferson are very irregular and intertwine around Marston Lake near Littleton (not far from Columbine High School ) so that in some districts the district changes several times. Well within the Denver boundaries, there are still streets that are administratively part of Arapahoe.
