entrance have to the depth of a cave (from Therion’s perspective)?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Entrances may occur anywhere in
underground survey network, at end of branch or mid branch (hole in roof of shallow
cave). Software should only take survey network as being of relevance to
the depth calculation. The flagging of entrances (or not) is quite an independent
concept that should not alter the way depth is calculated.<o:p></o:p></span></font></p>
