The Zion National Park blanket was introduced on September 1, 1926. 
This felt bound blanket came in six body colors: straw, drab, white,
camel hair, rose and delft blue, each with three rows of contrasting thick 
and thin paired stripes at both ends.  In 1929 the Zion National Park 
blanket was revised to use colored birds in a Hopi design border that 
complimented one of the seven available body colors.  The Zion Park
blanket reappeared in the 1950s and continued through 1965, but its 
design is not currently known.   

The only image presently available of a Zion Park blanket
is this poor black and white photo.  If you can provide a better photo,
please contact the woolmaster.
