<html> <head> <style></style> </head> <body class='hmmessage'> For those of you who may not be familiar with impact of cleaning on Topsoil Spring, here is what Phil Landis wrote in his 1988 report.<BR>  <BR> the spring's outer rim is oval-shaped and abour 3 x 2 feet.  This small intermittent spring remained in constant trickle overflow until I removed several large flat rocks from the bottom of the pool.  This clean-up exposed the spring's source which amounts to a group of perforations at the base of the soup-bowl shaped spring.  The pool then displayed random, periodic overflow separated by occasional pool levels 1-3 inches below overflow.  No bubbling was observed before or after cleanup.  Fluctuations in pool level did not appear to relate to eruptions of Grand Geyser.  I suggest the name Topsoil Spring because the grey-black sediment in the pool looks julst like the richest topsoil any farmer could ask for.<BR>  <BR> Lynn<BR> <BR> <HR id=stopSpelling> Date: Sat, 11 Jun 2011 06:22:01 -0700<BR>From: conanvandt@yahoo.com<BR>Subject: Re: [Geysers] Topsoil Spring<BR>To: geysers@lists.wallawalla.edu<BR><BR> <META name=Generator content="Microsoft SafeHTML"> <STYLE> .ExternalClass DIV {;} </STYLE> <DIV style="FONT-FAMILY: times new roman, new york, times, serif; FONT-SIZE: 12pt"> <DIV>Have we cleaned it out again recently?<BR></DIV> <DIV style="FONT-FAMILY: times new roman, new york, times, serif; FONT-SIZE: 12pt"><BR> <DIV style="FONT-FAMILY: arial, helvetica, sans-serif; FONT-SIZE: 10pt"><FONT size=2 face=Tahoma> <HR SIZE=1> <B><SPAN style="FONT-WEIGHT: bold">From:</SPAN></B> SnowMoon Photography <janet@snowmoon.us><BR><B><SPAN style="FONT-WEIGHT: bold">To:</SPAN></B> Geyser Observation Reports <geysers@lists.wallawalla.edu><BR><B><SPAN style="FONT-WEIGHT: bold">Sent:</SPAN></B> Fri, June 10, 2011 8:13:41 PM<BR><B><SPAN style="FONT-WEIGHT: bold">Subject:</SPAN></B> [Geysers] Topsoil Spring<BR></FONT><BR>I'm starting  to dive into the photos I took over my recent visit (the 4th-6th of June). One of the most striking changes (other than Oblong's change) was Topsoil Spring - every minute or two (got to talking rather than timing), the water level rises, bubbling increases and it starts to thump. A blog post with photos is here: http://www.geyserwatch.com/archives/1462 - it seems a bit of the scalloped edging has broken off as well over the winter.<BR><BR>Janet White<BR>SnowMoon Photography<BR>_______________________________________________<BR>Geysers mailing list<BR><A href="mailto:Geysers@lists.wallawalla.edu">Geysers@lists.wallawalla.edu</A><BR><A href="https://lists.wallawalla.edu/mailman/listinfo/geysers" target=_blank>https://lists.wallawalla.edu/mailman/listinfo/geysers</A><BR></DIV></DIV></DIV><BR>_______________________________________________ Geysers mailing list Geysers@lists.wallawalla.edu https://lists.wallawalla.edu/mailman/listinfo/geysers </body> </html>
