Revisiting these two Spanish tripoints from the comfort of my computer and the internet I have a lot more information to share now. Regrettably this means that I am now convinced that NEITHER of my two "finds" last September were actually of tripoints. :(
 
Lets take the northern one first - notably es2arlona. (The "comunidades autónomas " of Aragón, La Rioja and Navarra - see http://www.statoids.com/ues.html )
 
I have found the following evidence that makes it quite clear that the actual tripoint is, indeed, some distance to the north west of the road where I had stopped and taken the pictures that are at http://tinyurl.com/baglc, including ones of the supposed tripoint "mojón" which is obviously in the wrong place.
 
First I have found various topographical maps published by various agencies as follows:
 
http://tinyurl.com/78xsz is an extract from a 1:25000 topo map apparently published by a national agency
http://tinyurl.com/dhucl is effectively the same map but published by the government of La Rioja
http://tinyurl.com/dp73d is from a 1:50000 topo map
 
Now I have also found a wonderful site from the Spanish Ministry of Agriculture that has very detailed land division information superimposed on aerial photographs - this is at http://www.mapa.es/es/sig/pags/sigpac/intro.htm#inicio and leads you to various sites for each of the autonomous communities in Spain, some of which have better information than others.
 
First looking at the info from Navarra (http://sigpac.tracasa.es/navegar/) we can see in http://tinyurl.com/c8w8y the boundary of Navarra superimposed on a photo from 2003. In http://tinyurl.com/7zvv6 we have the same information on a photo from earlier (interesting to note the change in vegetation around the area of the tripoint during this interim period). It is also very interesting to note that the boundaries do not appear to be as straight as marked on the topo maps but tend to jog around quite a lot.
 
Comparing this with the info from Aragón (http://sigpac1.aragob.es/visor/) in picture http://tinyurl.com/bxy3e we start to get a hint of a possible exact location of the tripoint (maybe at the pointy bit just northwest of the abandoned railway track?).
 
However, adding in the info from La Rioja (http://sigpac.larioja.org/visor/) in picture http://tinyurl.com/7tuxr things get a bit confusing because if you now compare all three images you see that the little triangle shown on the Aragón picture crossing the railway overlaps with the land apparently claimed by Navarra thus raising the possibility that the actual tripoint is just south of the railway.
 
So another visit is most definitely called for - I hope to get back there in early May next year when I have another possible visit to Spain in the works.
 
Now - turning our attention a few km down the road to es2arcllo (Aragón, Castilla-León, La Rioja) which I had thought I had found at the roadside:
 
Looking at topo map http://tinyurl.com/brcqh (1:50000) it appears that the tripoint is not by the roadside at all but some distance to the east. This would explain the fact that there were only two readable province names on the marker I found at the roadside and why they were apparently inconsistently placed for marking a tripoint (I was led astray by the fact that this was a triangular cross section marker)
 
To confirm this lets look at some aerial photos:
 
http://tinyurl.com/caqdw is from La Rioja (unfortunately there is no actual photo at the probable tripoint although boundaries are shown) and http://tinyurl.com/7zys7 is from Aragón and http://tinyurl.com/933th from Castilla-León. These three photos tend confirm the information from the topo map and appear consistent and indicate that the tripoint is approximately where the track starts to turn towards the south on the right of the pictures. Once more it appears that the actual borders are a lot more "wiggly" than shown on the topo maps. So, again, another visit is called for here.

whoops
misunderstanding in process
for i didnt mean some distance in either direction
generally
but rather
specifically
in accordance with this best available map
http://www.larioja.org/sig/imagenes/5000/25tp2927.gif
unless i am misreading it or misinterpreting some of
the other data
between 110 & 137 meters up the bank & thru those
lovely woods
on a bearing somewhere between n13w & n39w from the
roadstone

or
averaging these ranges for starters & ease &
simplicity
make that about 124 meters bearing about n26w from the
roadstone
& only then fanning out & beating the bushes if
necessary for 15 or 20 meters in all directions

alternatively
get a gps fix on the target point directly from this
map if possible
but i think you might still have to beat the bushes in
that case too
so there might not be any advantage to doing it that
way

nor do i think it would just be a matter of luck but
of technique first & perhaps then luck too


but in any case you fully deserve our highest congrats
& thanx for having made this try at es2arcllo &
posting this beautiful report
which was the first known one of its kind in & indeed
from spain
as well as for your evidently luckier hit at es2arcala
just down the road
also the first of its kind
