Shadow Flicker
'Shadow flicker is the effect of the sun (low on the horizon) shining through the rotating blades of a wind turbine, casting a moving shadow.'
We were driving along here grabbing some other caches, and decided it wouldn't be a bad spot for a nice easy climb. Cache is a bison tube in a 3D-printed outer container about 4-5m up, easily spotted from the ground with a little searching. Accesible from both sides of the highway, and a 2WD friendly dirt road for a few kilometres to the cache.
