Labyrinth Mt via Lake Minotaur TH:

Tucked in a cirque a few miles east of Stevens Pass are Minotaur Lake, its immediate neighbor Theseus and overlooking Labyrinth Mountain. This group of alpine destinations, named for symbols in the Greek mythos, make for a great day hike and an excellent workout. 

From the Lake Minotaur Trailhead, travel roughly 1.5 miles up a steep trail to Minotaur Lake. For the Ascent Route, continue half a mile up to Labyrinth Mt for a total ascent of 2477'. 

Described by Jojo Klein:

Starting at the cablecar station of the 'Nebelhornbahn' in the valley, the goal is to clap the cross at the top of the Rubihorn and going all the way back to the cablecar station.

There is no route or way predetermined. Just follow the fastest track you can find. The only importance is to start at the Nebelhornbahn in the valley, clapping the cross at the top of the Rubihorn and running back to the start. 

Here in Oberstdorf, we call this challenge 'Rock the Rubi'.
