The Vinland Sagas are two very short (compared to Egil's or Njal's or some of the others) Sagas that tell about the earliest white explorers to arrive in North America. The Vinland saga is actually an excerpt from a larger work about some Norweigan King so it doesn't fit the usual setup afforded most of the sagas. The Saga of Erik the Red talks more about Greenland and a teensy bit about Vinland.
I really enjoyed these sagas but I wish they were longer and had more details. Its amazing to think about these incredibly tough Vikings arriving in North America like 500 years before Columbus and in a lot better shape too.
