MADISON, Wisc. (AP) -

A legislative committee is studying changes to Wisconsin law protecting burial sites after a Republican bill that would have allowed quarry owners to excavate American Indian mounds died last session.

The measure would have allowed Wigra Stone and Redi-Mix to excavate Ho-Chunk Nation burial mounds that lie in a Dane County quarry to prove whether human remains are really present.

A legislative committee comprised of leaders form both parties created a committee after the bill died to study possible changes to burial site protection.

The committee has met only once and hasn't set firm goals. Possible discussion areas, however, include making burial site locations more accessible to land developers, the size of development buffer zones around catalogues sites and allowing minor disturbances at sites.
