This is one kind of stab dial.
If one makes the same stabs into other surfaces, maintaining the
same alignment, it can be seen that they would work as well, even
if the stabs were scattered about rather than in order.
Since it is difficult to look fully into the stab marks, some

Dear Fred,
How neat! I hope to hear more on this.
I've come up with a very simplified Equatorial Stab Dial that seems,
so far, to overcome a number of the peculiarities of the dial as well as
being very easy to fabricate. Very little sun here so far to test it. I'll
send you
eek now. The
basic concepts have evolved quite a bit so, if the models actually
work I'll write up something.
Thanks for your interest!

Dear Sun/Shadow watchers,
I've put up on my site at
http://www.vandp.com/stabdialinfo.pdf
a short but information filled article on the evolution of stab dials.
This is a first draft so any and all comments are welcome. I've not
included the details of most of the calculations at this point,

Hi Edley:
The most interesting, and only "stab" Dial I've ever heard about is the
famous one at Chaco Canyon in Arizona (That's a neat term for them, or how
about "dagger dial"?) We saw a great video on it at the Tucson NASS
conference. It showed a time lapse m

Dear Shadow Watchers,
Since there seems some interest in stab dials I include this comment
on an meridianal analemma in that form. If there are others involved
in stab/groove/slit dials or that have seen literature regarding them I'd
enjoy hearing about it.

Dear Shadow/Light watchers,
This idea seemed interesting enough I thought you might like it.

This is an idea for a dial that I like very much.

Two locations where actual buildings had the Sun or Moon shine deeply into them at certain times are
In regards to the spiral representing 18.6 years (and not 18.5 or some other close number), I believe the answer is that the observations are directly tied to the 18.6 year cycle. So, if the observations were properly recorded, the spiral would indeed represent 18.6 years.

Hi Albert,
Yes, after looking at the site, I agree with you. I would clearly
consider it a "Stab Dial". Your definition is also very clear and I
believe complete. It was nice to see pictures of one.
Thanks!

My opinion is that many archeoastronomy sites were observational in origin. I still agree
that this is a type of stab dial.

The photo at top of the linked page makes me feel certain that the petroglyph was intentionall drawn to represent the location of the Sun in the sky.
