MISS  OGILVIE  ON  THE  WENGEN  AND 
[Feb.  1893, 
I  have  also  drawn  a  parallel  section  in  the  Gader  Talley  below 
the  pass.  As  the  fault  which  separates  the  inverted  system  from 
that  of  Gardenazza  does  not  strike  exactly  perpendicular  (i.  e.  east 
and  west)  to  the  plane  of  the  section,  but  W.S.W.  and  N.N.E.,  the 
St.  Cassian  and  Wengen  Beds  of  the  Gardenazza  system  exposed  in 
the  Abtey  Muren  extend  farther  north  than  in  the  Pass  section. 
Recapitulating  briefly  the  tectonic  relations  in  the  Lpper 
Enneberg  : — 
(1)  We  have  in  Abtey,  west  of  Kreuz  Kofi,  a  region  of  less  sinking, 
where  Wengen  and  St.  Cassian  Beds  possess  an  extended  outcrop. 
The  same  result  is  attained  in  Prelongei,  and  the  St.  Cassian  strata 
are  still  more  favourably  exposed  by  the  folding  of  the  whole  series 
into  the  form  of  a  flat  syncline.  Towards  the  Buchenstein  Talley  the 
Prelongei  syncline  passes  into  an  anticline,  and,  erosion  having  removed 
the  higher  beds,  the  older  Triassic  strata  are  there  fully  exposed. 
The  system  of  older  Trias  which  comes  over  the  Groden  Pass 
separates  the  Wengen  and  St.  Cassian  strata  in  Abtey  from  those 
of  Prelongei ;  and  the  strike  of  the  two  systems  is  different :  in 
Abtey  the  strike  is  north  and  south,  on  Prelongei  it  is  east  and  west. 
(2)  St.  Cassian  strata  lie  conformably  below  Schlern  Dolomite  on 
the  southern  side  of  Sett  Sass,  at  various  parts  of  Sella,  Gardenazza, 
and  Zwischenkofl,  at  one  part  of  La  Tarella,  at  Centurinus  Spitz, 
Lagazuoi,  and  Tra  i  Sassi.  In  all  other  places  the  Schlern  Dolomite 
has  either  been  removed  by  erosion  (Prelongei  and  Abtey),  or  it  has 
been  faulted  down. 
(3)  At  Heiligkreuz  Kirche,  on  the  western  side  of  Sett  Sass,  and 
at  Talparola,  the  Raibl  strata  do  not  lie  conformably  upon  St.  Cassian 
beds,  but  beside  them,  separated  by  faults. 
(iii.)  The  District  of  Cortina  and  Falzarego. 
The  Cortina  map  (B,  facing  p.  28)  forms  the  easterly  continuation 
of  the  Sett  Sass  district  and  embraces  the  high-lying  valley  of 
Falzarego  between  the  Tofana  and  Kuvolau  massifs ,  and  the  western 
portion  of  the  Cortina  hollow.  Over  an  extent  of  ground  measuring 
12  miles  as  the  crow  flies,  from  Falzarego  northward  to  Schwalben 
Kofi,  one  meets  no  other  rocks  than  Dachstein  Dolomite,  Jurassic, 
and  Cretaceous  strata. 
The  road  from  St.  Cassian  to  Ospizio  in  Falzarego  leads  over 
Talparola  and  Tra  i  Sassi.  As  was  shown  in  discussing  the  Pre¬ 
longei  map  (see  pp.  20.  60),  the  fault  separating  the  "V  alparola  and 
Lagazuoi  system  from  Sett  Sass  passes  eastward  towards  F alzarego, 
while  the  north-and-south  Heiligkreuz  fault  bends  round  north  of 
the  Sore  Bach,  and  is  continued  eastward  over  Monte  Cavallo. 
These  relations  may  be  thus  shortly  represented  : —
