in season 6 episode 9 of the curse of
Oak Island the Fellowship of the dig
fully on Earth's the mysterious u-shaped
structure at Smith's Cove much of the
structure appears to be ensconced in
what terry matheson describes his
clay-rich till evoking the blue clay
found in the money pit by the Onslow
company in the early 1800s
if this till is indeed the same sort of
blue clay found in the money pit then
three possibilities regarding the nature
of the u-shaped structure seem to
present themselves one the structure
constitutes the remains of either the
Truro company cofferdam built in the
summer of 1850 or the Halifax company
cofferdam built in 1866 the clay rich
till being either blue clay extracted
from the money pit itself half a century
prior by the Onslow company or fresh
clay taken from the source which
supplied the original depositors with
their own material this theory
corresponds with the findings of Dan
Blankenship's old partner David Tobias
and engineer les McFly who in the year
2000 carbon dated a piece of the
u-shaped structure to 1860 plus or minus
30 years a second possibility is that
the structure is a relic of the original
depositors who employed the same blue
clay they used in the money pit in its
construction in her 2015 book Oak Island
mystery solved Canadian author Joyce
teal proposed a third theory which holds
that the u-shaped structure was
constructed not by the original
depositors nor by previous searchers but
rather by local British colonists who
designed it as a brace to keep tar kilns
in place later on Rob Hyslop and Ryan
Levine of azimuth consulting limited
returned to Oak Island to present the
results of their lidar scan of the
supposed 90-foot stone which they
conducted in the previous episode
although Rob and Ryan scan revealed a
line which they suggested might
transform the carved end into an
upside-down a the letters L&N being the
only visible characters carved on the
stone surface it failed to reveal any of
the mysterious inscriptions the 90-foot
stone was said to have borne next Jack
Begley and Gary Drayton
secure the services of diver Tony
Sampson who takes them in his boat to
nearby Apple Island there the treasure
hunters discover three large boulders at
the coordinates indicated on the star
map introduced by dr. Travis Taylor in
the previous episode they proceeded to
conduct a metal detecting operation on
Apple Island during which Gary Drayton
discovers a number of targets one of
them non-ferrous the treasure hunters
agree that they ought to apply for a
permit which will allow them to dig for
these targets later at the money pit
area choice drilling sinks a hole called
ke 5.5 in an attempt to intersect this
shaft six tunnel an old searcher tunnel
which leads to the original money pit
sure enough a court sample taken from
the hole reveals wood from 118 to 124
feet and so what is located slightly
deeper than expected the treasure
hunters surmised that some of it might
comprise timber from the collapsed money
pit near the end of the episode Laird
Niven Terry Matheson and bill eager
heart discover a wooden wall composed of
vertically aligned Timbers buried
beneath Smith's Cove there are no
records of previous searchers having
discovered or constructed this wall
suggesting that it might constitute
original workings this underground wall
at Smith's Cove evokes the wooden wall
dat Fred Nolan claimed to have
discovered in the Oak Island swamp in
1969 for which the crew fruitlessly
searched in season 3 episode 8 Nolan had
described this structure as a 12 foot
tall 12 foot long wooden wall made of
square sawn Timbers and claimed that he
had discovered it in the southern part
of the swamp a short distance from the
beach in that older episode it was
suggested that the swamp wall might be
evidence of the swamps artificiality
