[Vocabulary] Something in the ground

[Cynthia Garett]

Hello,

I cannot seem to understand what director Peter Jackson is saying at 1.06.50 in this movie. "Braemar station was pretty difficult working conditions for the cast and the crew because the ??? in the ground is very uneven". This is the ling of the movie: Making Of "The Hobbit: An Unexpected Journey" Full | All of Production Blogs 1-9 - YouTube

Thank you. Merry Christmas!

The word is "tussock", a type of grass that tends to grow in clumps, and which you can see in the film.
