Terrain Moving Effect - Stationary Player (only moves on X axis), Obstacles Moving Towards the Player

Hi Everyone!

I am working on an infinite skiing game for iOS/Android. I have chosen to have the player be stationary with the incoming obstacles moving towards the player. This will avoid floating point issues if the player is very far away from (0,0). So far I have been working on effects to make the player appear to be moving, such as a line render behind the player.

What I am struggling with is creating an effect that the player is moving forward in the world. I was hoping for some tips of advice to give the effect of my terrain moving as my player remains stationary. Here is a link to a demo of my game in its current state:
