Many years ago, some yurts were built for the Folk Festival on the Mall, produced by the Smithsonian in DC. Not the felt type of yurts, but wooden ones with dirt-and-grass roofs. After the festival, the yurts were moved to Glen Echo Park and now house some of their artisans-in-residence. Some of the roofs are real works of art by now, with flowering mosses etc.
The following was co-written by Don Nichols (the concertina-repair wizard) and Tom McHenry, to the tune of the Chrisian Harmony/Sacred Harp version:
Hail the yurt so long neglected
Hail the roof in mowing's need
See the turf that falls from heaven
Never more to go to seed
Weeds upon the roof are sprouting
Ev'ry day there's more & more
And a goat is munching, is munching, is munching
And a goat is munching the yurt next door.
