Origami Tessellation: Mountain Climbing

Searching for something simple, yet interesting, I came up with this pattern. 

The weather lately, has not been conducive to intricate designs. So I was hungry for something new and intriguing that I could fold without the dampness interfering. 

I came up with a rhombus with triangles twisting at all four axes.

In order to repeat the pattern, I used the corners on the outside of the triangle twists to facilitate the next array. 

The shapes overlap each other in some areas. It's folders choice how they land from top to bottom. 

It's pretty easy to fold, as was my intention. 

It has interesting layers and weaving on the reverse side. 

It's just one of those wonderfully simple designs that looks much more tricky than it actually is. 

Crease pattern included below.
