When I was younger I saw the Intiwatana in Machu Picchu, a type of sundial with varying planes and angles. The Incas used it as an astronomical clock or calendar.
The name sundial/ravine is from a found poem I made a few years ago. The two words side by side mean time and abundance. Sundial measures the sun passing, as shadows on a round object, and ravine, is a narrow landform, usually a slope of rocks, withered by water. The passing of a stream signifies a journey where small pebbles, little fishies and even wildflowers can be found. The way a ravine appears might change in later years. In a way, I hopes to capture what was lost and gained as days moves to night in this space. Also, I like the sound of the parallel words.
Intiwatana, is a Quechua word meaning tying up the sun.
