In and around the early 1900s, the Government of Canada used Crown grants to issue interests in land. If a Crown grant includes rights to mines and minerals, including quartz, in the location of the grant, quartz claims cannot be staked over the location of that Crown grant. If the Crown grant included both placer and quartz rights then neither type of claim can be staked over the Crown grant. This data represents the location of crown grants in the Yukon.

Game Management Areas (GMAs) are legal boundaries that define an area within which big game management objectives can be met through the setting of area-specific regulations. In other words, GMAs are used to manage Yukon wildlife species. GMAs are a combination of Game Management Zone (GMZ or Zone) and Game Management Subzone (GMS or Subzone). There are 443 GMAs in the Yukon which are grouped together into 11 Zones. In general, Zone boundaries follow highway centre lines and Subzone boundaries follow creeks and rivers. In effect, GMAs delineate mountain blocks, which reflects their original use as sheep management units. Despite this original intent, GMAs are now used to manage all species of Yukon wildlife. With the exception of National Parks, the entire Yukon is covered by GMAs. This data was built using the 1:250,000 National Topographic Data Base (NTDB) as the digitizing base.
