A boy named Sam Gribley runs away from his home in [[BigApplesauce New York]] to live in the Catskill Mountains. The book documents his time up in the Catskills, and is a detailed and fairly realistic take on how to go about wilderness survival.

Written by Creator/JeanCraigheadGeorge in 1959, it received a [[UsefulNotes/NewberyMedal Newbery Honor]], and was adapted into a somewhat-obscure film ten years later. As of now there are four sequels to ''Literature/MySideOfTheMountain'': the direct sequel ''On the Far Side of the Mountain'' (with no relation to [[ComicStrip/TheFarSide Gary Larson's comic]]), and the three sequels told from the perspective of falcons, ''Frightful's Mountain'', ''Frightful's Daughter'', and ''Frightful's Daughter Meets the Baron Weasel''.

It was made into a film in 1969. Many things were changed, including Sam's motivation for going to the mountain. He's no longer a runaway but is instead a budding scientist seeking to learn from nature. He also returns home at the end instead of having his family join him in the wilderness.
!!Provides examples of:

* AllAnimalsAreDomesticated: While falcons can be domesticated, most peregrines aren't as social as Frightful and it's hardly as easy as Sam makes it seem.
* ArborealAbode: Sam makes his new home in the base of a hollowed out tree.
* ABoyAndHisX: Sam and his falcon Frightful are each other's constant companions.
* DeathByAdaptation: At the end of the movie version of ''Literature/MySideOfTheMountain'', Frightful the hawk gets shot and dies. In the book, she not only lives, but ends up with ''three sequels focusing on her.''
* EgomaniacHunter: Sam scavenges a few deer off these guys.
* HardWorkHardlyWorks: It could be part of his personality, taking everything in stride, but Sam never seems to encounter any major setbacks. Even getting scurvy and carbon monoxide poisoning aren't shown as anything but minor, temporary and maybe even funny obstacles.
* KidsWildernessEpic: The story is Sam's attempt to live off the land while living in a tree and the adventures he has.
* MoralGuardians: Initially Creator/JeanCraigheadGeorge had trouble getting this book published because publishers thought MoralGuardians would object to the book on the grounds that it encouraged children to run away from home and live in the woods. Whether or not this was justified, at least George explained quite clearly that Sam ''did'' know how to live off the land and find food, even before he left. Furthermore, the actual steps required in living off the land are explained quite clearly as involving ''a lot'' of work. Presumably most children reading this book can read between the lines and find the message "Sam knows how to do this, had to work ''a lot'', and still got sick and ran into trouble. Unless you know what Sam does, you won't make it, so stay home."
* NemeanSkinning: Sam kills a deer through use of traps to make himself clothes. The process of tanning its hide is long, complicated, and detailed. Kid has a good memory.
* NobleBirdOfPrey: ''[[NamesToRunAwayFromReallyFast Frightful]]'' is a majestic creature, as are other falcons.
* TheRunaway: Sam has a perfect relationship with his parents yet decides to run away to the Catskill Mountain and live in a hollowed out tree for the pure adventure of it all.
* RunAwayHideAway: Sam constructs his own hideaway, and his desire to create one where he can live off the land is most of the reason he ran away in the first place.
* ShownTheirWork: It's pretty clear that the author did a lot of research on how to go about living in the woods by yourself before writing this book. A possible [[AnAesop Aesop]] that the author may have been attempting to convey with this effort is "Sam knows what he's doing. You don't. Please don't run away from home and try living off the land."
* SmellySkunk: Sam learns an important lesson about why you shouldn't feed wild animals in part because of this trope.
* SlidingScaleOfIdealismVersusCynicism: Not as far in the idealistic camp as other [[KidsWildernessEpic Kids Wilderness Epics]] due to Sam's frequent mishaps, but they're played off as humorous minor setbacks rather than costly and devastating, and the book has a very happy ending.
%%* WeaselMascot: Baron.
* {{Xenofiction}}: All of the novels dealing with Frightful or her daughter are from the prespective of a falcon.
* YourTomcatIsPregnant: Jesse Coon James the raccoon is initially thought to be a male raccoon, but after Sam finds out that Jesse is pregnant, he supposes that she's a "girl Jesse" instead.
