Unusual stripes in Altai Krai. A Wikimedia image description offers an explanation:

> In June 2014, the crew aboard the International Space Station (ISS) called down to Houston to ask for an explanation of this strange pattern of spikes crossing the Kulunda Steppe in central Russia. The “spikes” are a prominent visual feature when the ISS is at the top of its orbit (52 degrees north, the highest latitude flown over by the spacecraft). Scientists at NASA’s Johnson Space Center were able to provide an answer. 
> The linear zones in the image are gentle folds in the surface rocks of the area; they lie slightly lower than the surrounding, lighter-toned agricultural lands. The dark zones are forested with pines and dotted with salt-rich lakes.
