What are the Roman Catholic pilgrimages in Northern America? In France there are several "formal" and organised catholic pilgrimage each year to Lourdes, Chartres, Vezelay for boy-scouts and other shrines that occures a few times, sometimes even once a year and are an occasion of gathering around faith. What are, if they exist, the organised pilgrimages equivalent in America? Is there a database of them?

I googled a bit and only found the Marian Days for the Vietnamese American Roman Catholics.

By catholic I mean the branch of the Christian Church that accepts the Pope as its leader and is based in the Vatican in Rome.
The Society of St. Pius X has been hosting annual U.S. pilgrimages for nearly two decades. From their site:

There's also a Starkenburg Pilgrimage and an Auriesville, NY, pilgrimage, which honors "a group of Jesuit priests and religious [who] were martyred by the Iroquois Indians" "over 400 years ago".

The American branch of Tradition, Family, and Property (TFP), a lay Catholic group, also does Marian pilgrimages.
