arrowhead

The natives used to hammer the metal into arrowheads, using heavy stones.

土著人以前总是用沉重的石把这种金属锤打成箭。

During their four seasons in Range Creek, the teams had plotted the GPS coordinates of every site they'd found and recorded the location of every potsherd, arrowhead, and metate.

对于牧溪谷的每个季节，该小组都已在每个地方设定了GPS，他们记录每一个具有考古价值的陶片，箭和研磨石被发现的具体位置。
