Hello --<br><br>I just found your site and am very impressed. Camping and backpacking have been a part of my life since the late fifties (I am 52 now). In reading alot of the past posts I have not seen any information about cave fires. Does anyone know a rule-of-thumb about placement of fires to achieve the best draft? I am thinking mostly of the desert southwest in caves which do not have previous fire scars (on the ground and/or ceiling). I do not advocate scarring caves with new fires except in a survival situation. Since caves "breathe," improper placement might draw the smoke into the cave, thus running you out. Maybe Chris K, being an archaeologist, would know about any Native American methods.<br><br>Thanks,<br><br>Arinite7
