The 2013 HALS Challenge flyer is on the ASLA website.
Read the article about the results of the 2012 Challenge : "The Field"
The tools needed to prepare an entry for the Challenge are:
-HALS 101 Brochure
-Preparing a HALS History Brochure
-HALS Short Form History Template
Downloadable template here
I also recommend anyone interested in HALS to check out the HALS National Park Service site.
And the Northern California HALS Chapter website that includes 16 HALS Challenge entries from 2012 in pdf format.
