These slides are part of ongoing investigation on
the technologies, relationships, and sequences of
the earliest projectile point forms in western
North America. The purpose is to examine known
technological forms that could possibly be
ancestral to Clovis. Given the theory that the
human populations in North America that developed
the Clovis point and other PaleoIndian lithics
came from the northwest via Beringia, it stands
to reason there should be more similarities
between the earliest far-western US point forms
and whatever immediately preceded, and possibly
led to, Clovis, than in other regions. The
following is an attempt to explore these possible
relationships. It is based principally on outer
dimensions for width and thickness as well as
outline shape. The comparison of different early
point styles from the western US to each other as
well as the Alaskan Mesa and Sluiceway point
styles is key. The western point examples used
include Haskett and Clovis, or Clovis-like, from
the Great Basin and one Clovis-like point from
Blackwater Draw, New Mexico.

  • The theory as it stands is based on the following
    premises
  • Clovis evolved from thick body point styles.
  • The early thick body point styles include Mesa,
    Haskett, Agate Basin, and likely El Jobo.
  • Some thick body point styles persisted on after
    Clovis.
  • There are two distinct Clovis styles one early
    (thick) and one late (thin.)
  • Many early, or thick, Clovis points are actually
    concavely rebased Haskett or Agate Basin points.
  • Haskett points from the far west and northwest
    are separate and distinct from other western
    stemmed points such as Lake Mojave.
  • Clovis points form the far west and northwest are
    separate and distinct from the Blackrock Concave
    Base series.
  • What is clear is that remarkable similarities
    exist between Haskett, Agate Basin, Mesa, and
    some Clovis point forms from the Great Basin as
    well as at least one Blackwater Draw Clovis
    point.

This analysis represents the beginning of an
attempt to understand a possible scenario and
investigate possible theories. It is preliminary
and subject to significant changes as more
becomes understood. Nomenclature used for the
artifacts depicted on the following slides
include convex-base Haskett points (CVX) from the
southern and central Great Basin, one point from
Blackwater Draw (BWD,) one Mesa point, and three
Clovis-like points (CL) from the southern and
central Great Basin. The term Clovis-like is
intentional to avoid the confusion commonly
encountered in identifying western Clovis points
due to variability which this analysis hopefully
begins to address. The Blackwater Draw and Mesa
points depicted are photos of plastic casts.
The starting point in these slides is to
compare and contrast point forms that have
roughly the same W/T ratios to investigate other
similarities. Statistical distributions of values
is found elsewhere. The slides contain many
animations. Using the space bar, mouse click, or
up/down arrows (slowly) progress through the
slides and animations.

The sequences on slides 6 and 7 compare a very
large Haskett point that was recovered in two
pieces to a complete Clovis point that was almost
certainly refurbished from a much larger point.
Widest Point of Haskett 35 mm
Not a perfect fit- Possibly an unrelated Late
Clovis point??
Also possible This Clovis point shows slight hint
of diagonal Outré Passé flaking though Not
typical for Haskett

Better, but the dimensions still arent perfect
If the Clovis was the same width as the Haskett

Slide 8 compares the same Haskett point to a
proximal end of a Thick Clovis-like point. The
points are shown with a true relative scale. The
W/T ratios are very close.

Slide 9 compares another Thick Clovis-like point
with the large Haskett. The two have virtually
identical W/T ratios. This point is possibly a
refurbished proximal base that was turned
around.
Maybe

The Great Basin thinned point has similarities to
Alaskan Mesa Points and fits nicely with the
Hasketts
Slide 10 compares two Haskett bases with a thick
Clovis-like base and the Mesa point

a Thick Clovis and a large Haskett base

They both appear to be heavily reworked but from
opposite ends
Or, They were both worked from the same end but
in opposite directions

All Three were broken at the Same Place
Due to similar hafting methods or sockets??
