Riverdale is the setting for most of the characters that appear in Archie Comics. Riverdale's exact placement in the United States is uncertain, as conflicting details have been given over the years in the comics as to its location. However, it’s believed to be upstate New York. The Blossom family is involved in the maple syrup business, existing in only upstate New York and Canada in the real world (whoever wrote this must not be familiar with New England as this isn't even close to accurate) . There is also a reference to the family from the north being from Montreal. Montreal is directly North of upstate New York by a couple of hours.

Riverdale High

Riverdale High School is the local educational institution of Riverdale where Archie and his friends attend grade 10. It is based on what was Haverhill High School in Haverhill, Massachusetts. The building still stands, although is now Haverhill's City Hall. Riverdale High's walls sport a blue and green color scheme, although the school colors are officially blue and gold. Frequently-seen locations on school grounds include its many classrooms, cafeteria, gymnasium, athletic field, chemistry lab, principal’s office, and the office of the school newspaper, The Blue and Gold.
Only a few of Riverdale High's staff appear regularly. These include school principal Mr. Weatherbee, homeroom teacher Miss Grundy, chemistry teacher Mr. Flutesnoot, history teacher Miss Haggly, physical education teachers Coach Kleats and Coach Clayton, cafeteria cook Miss Beazley, custodian Mr. Svenson, secretary Miss Phlips, and superintendent of schools Mr. Hassle.
