<h2>Stellerweghöhlensystem: deep side leads</h2>
|
|
|
|
<h3><a name="offdford">Dartford Tunnel</a></h3>
|
|
|
|
<p>There are several small tubes leading off both right and left near the
|
|
start of <a href="deepwy.htm#dartford">Dartford Tunnel</a> [<a name="C1982-41-00"
|
|
href="qmlist.htm#C1982-41-00">C1982-41-00</a>], also downhill, but none of these
|
|
crawls/stoops have been pushed to a conclusion. There may also be high leads
|
|
to the left 40m [<a name="C1982-41-01" href="qmlist.htm#C1982-41-01">C1982-41-01</a>] and 60m
|
|
[<a name="C1982-41-02" href="qmlist.htm#C1982-41-02">C1982-41-02</a>] from the start.</p>
|
|
|
|
<p>Where Dartford Tunnel turns abruptly right (NW) and changes into a high
|
|
rift, there is a possiblity of a passage to the left, about 6m up the wall,
|
|
continuing the line of the rift in the opposite direction [<a name="C1982-41-04"
|
|
href="qmlist.htm#C1982-41-04">C1982-41-04</a>] to the SE. This NW-SE joint is parallel
|
|
with the Big Rift of Stellerweg, and seems to be a major influence in this
|
|
area.</p>
|
|
|
|
<p>The joint-guided rift ends abruptly at a T-junction where the main way
|
|
is left in SW-trending vadose canyon. To the right is also big passage,
|
|
leading Northeast to an aven with an inlet [<a name="C1982-41-05"
|
|
href="qmlist.htm#C1982-41-05">C1982-41-05</a>], but no way on. On the main way, at a 4m
|
|
climb down, a passage comes in from the right, also NE; this may be followed
|
|
to a low area of mud and boulders [<a name="C1982-41-06"
|
|
href="qmlist.htm#C1982-41-06">C1982-41-06</a>] with no continuation.</p>
|
|
|
|
<h3>Confluence Area (1982)</h3>
|
|
|
|
<p>Where the Purgatory Bypass finally intersects the canyon of the stream
|
|
entering at the Confluence, the main way is to the left on a ledge. No
|
|
attempt has apparently been made to follow the canyon to the right at high
|
|
level [<a name="C1982-41-12" href="qmlist.htm#C1982-41-12">C1982-41-12</a>], perhaps because
|
|
of its angle and lack of friction.</p>
|
|
|
|
<p>The main way crosses the canyon to a terrace, and drops down from here to
|
|
the Confluence from a corner. If, instead of dropping down here, the terrace
|
|
is followed round the corner to the right, it leads to a dry vadose trench in
|
|
the floor and then a traverse above the main streamway. <b><a id="rampant">Rampant
|
|
Passage</a></b> starts near this corner and rises as a large dry passage, 7m high
|
|
and 2m wide. This climbs 30m in its 65m length to emerge at a huge chamber,
|
|
<b>Cologne Cathedral (Köln Dom)</b> approximately 15m in diameter and
|
|
apparently 20m high. A dangerous climb, c10, c5m leads to 25m of passage
|
|
ending in the huge 30m high Echo Aven [<a name="C1982-41-14"
|
|
href="qmlist.htm#C1982-41-14">C1982-41-14</a>]. It's not entirely clear whether there is
|
|
a way on [<a name="C1982-41-13" href="qmlist.htm#C1982-41-13">C1982-41-13</a>] in the roof of
|
|
Köln Dom.</p>
|
|
|
|
<p>Many of the passages in these levels contain dead bats, perhaps suggesting
|
|
a lower entrance, though this seems unlikely to be nearby. Some of the deeper
|
|
passages of <a href="../../noinfo/1623/78.htm">Schwabenschacht (1623/78)</a> are near this
|
|
area, perhaps 200m above the Confluence. The top of Echo Aven is near to
|
|
halfway to bridging this gap, which suggests the possibility of a connection
|
|
in the next few years.</p>
|
|
|
|
<p>The climb down from the Bypass lands at the junction of the Purgatory
|
|
water and an inlet [<a name="C1981-41-07" href="qmlist.htm#C1981-41-07">C1981-41-07</a>] which
|
|
can be followed upstream (ESE) in a passage similar to the Purgatory, until
|
|
soon after a 7m climb up, the streamway divides twice and becomes too small
|
|
to follow. This is thought to be the Stellerweg water, last seen in Junction
|
|
Chamber, but is likely also to include water from various inlets and floor
|
|
trenches seen in Dartford Tunnel, as there are no inlets in the Purgatory
|
|
itself.</p>
|
|
|
|
<h3>Stream Inlets below the Confluence (1982)</h3>
|
|
|
|
<p>Downstream of the Confluence, just after the first (4m) wet climb is the
|
|
entry of a dry inlet on the right, which leads back towards the Confluence,
|
|
but was not pushed to a conclusion [<a name="C1982-41-15"
|
|
href="qmlist.htm#C1982-41-15">C1982-41-15</a>]. Shortly downstream, below the 7m pitch,
|
|
the streamway feeding the cascade on the left [<a name="C1982-41-16"
|
|
href="qmlist.htm#C1982-41-16">C1982-41-16</a>] remains unexplored (this is shown on the
|
|
right on the survey, not the left).</p>
|
|
|
|
<p>Where the sump bypass drops back to the main stream, the continuing way up
|
|
is unexplored [<a name="C1981-41-22" href="qmlist.htm#C1981-41-22">C1981-41-22</a>]. Halfway
|
|
between the next 3m pitch and the Twelve Foot Climb, (50m from each) another
|
|
inlet enters from high up, this time on the right [<a name="C1981-41-23"
|
|
href="qmlist.htm#C1981-41-23">C1981-41-23</a>]. Much further on, another unexplored inlet
|
|
up on the left [<a name="C1981-41-24" href="qmlist.htm#C1981-41-24">C1981-41-24</a>], shortly
|
|
precedes the Subtle Approach Pitch.</p>
