This song is about a person making a change when she realizes that she has been betrayed by someone/group of people to whom she has given everything.

Landslide refers to the collapse of the relationship when she withdraws her love after a person/group betrays her.

She had dedicated her whole life to building this relationship (climbed a mountain), but the betrayal has caused her to stop (turn around) and take a hard look at how she sees herself and how others see her (her reflection).

This betrayal causes her to see herself as alone, unloved, and unappreciated--"in the snow-covered mountains," so she decides to withdraw her love (I take my love, and I take it down), which brings a sudden, massive end/landslide to the relationship.

She wonders what love is, if she can rise above this betrayal (Can the child within my heart rise above?), and if she can make this change and still continue in a positive way with her life (Can I sail through the changin' ocean tides? Can I handle the seasons of my life?).

She says that she has built her entire life around this person/group (I built my life around you), so taking down her love from this person/group does not come easy, but now she is older and has grown, so can make the change because she will no longer give to this person/group after he/they have abandoned her alone "in the snow-covered mountains."

She tells this person/group to walk away from this relationship (So take your love, take it down) because if he/they stop and reflect on the relationship and how the betrayal has left her abandoned, they will understand this landslide--why she has withdrawn her love and why the relationship has ended.

Incredible interpretation. I wonder how you came to it. Personal experience? Philosophical perspective? Intuition? What about the comment she says in a live recording where she says, "this is for you, Daddy." That was very telling,
