Dean Winchester: Well, hell you know I'm in!
- Goof (errors in geography): They say this episode takes place in the area around Grand Junction, but the problem is that the geography of that area is all desert, not full of trees like they implied in the episode.
- Goof (continuity error): In the beginning, when Tommy is filming his message to Hailey, his dialogue says: "Hey, Hailey. Day 6. We're still out near Blackwater Ridge. We're fine, keeping safe, so don't worry. Talk to you tomorrow." But when Hailey plays the recording for Dean and Sam, the message becomes: "Hey, Hailey. Day 6. We're still out near Blackwater Ridge. We're fine, keeping safe, so don't worry, okay? Talk to you tomorrow."
- Goof (errors made by characters, possibly deliberate errors by the filmmakers): When Sam and Dean first introduce themselves to Hailey, Dean says his name is Dean but the name on his ID says Samuel Cole.
- Goof (errors made by characters, possibly deliberate errors by the filmmakers): Upon arriving in Colorado, while the Winchester brothers are at the ranger station gathering information, Sam states that they are natural resource majors at UC-Boulder. The school is actually known as CU-Boulder.
- Goof (factual errors): The brothers use Anasazi symbols to fight the Wendigo in Colorado when the tribes were actually located in the Southwest. Dean says that Wendigo are typically found in the Northeast of the country (Minnesota) and he's never heard of one as far west as Colorado.
- In the beginning two guys are playing a first person shooter video game against each other and one claiming the other is cheating. A reference to the pilot of Threat Matrix. Executive producer John Shiban was a writer for that show.
- The book Tommy is reading in the beginning is: "The Hero with a Thousand Faces" by Joseph Campbell (III). In this book Campbell's unique perspectives examine the world's complex and interwoven mythology, folklore and religion, providing an understanding of the essence and genesis of humanness.
- SPOILER: Body count: 4
- When discussing how wendigos came about, Ben refers to the Donner Party. The Donner Party was a group of pioneers headed west in a wagon train to California in the winter of 1846 who became trapped by an early snow storm while crossing the Sierra Nevada Mountains. They were stranded for four months and resorted to cannibalism to survive.
- Sam's deceased girlfriend's full name is Jessica Lee Moore as seen on her tombstone in this episode.
