I came across some marketing material for the Western Colorado Community Foundation recently which included their logo - a spiral circle.

On their logo they have this to say:

Our Logo… The circle reflects a sense of community and our connectedness to others.

The spiral reflects the power of endowment, a permanent gift that keeps on giving.

The petroglyph symbolizes those who have been here before us and who have left their mark

Their staff and board of directors are listed, but I don't recognize any of the names.

There might be nothing here, but with a logo like that I imagine that it's worth more than a passing glance by folks with an eye for this sort of digging.
