In  the  vicinity  of  Glendale  coal  occurs  in  the  upper  part  of  the 
rocks  of  Colorado  age,  and  prospects  have  been  opened  northeast  and 
southeast  of  the  town,  adjacent  to  the  Sevier  fault. 
C.  Levanger  has  opened  a  prospect  (No.  15),  in  sec.  26, T.  40  S.,  R. 
7  W.,  in  which  the  following  section  was  measured,  the  base  of  the 
coal  not  being  exposed:

QUALITY    OF    THE    COAL. 
The  Colob  coals  are  deep  black  and  have  a  shiny  luster.  They  are 
slick  and  do  not  soil  the  hands  like  better  grades  of  bituminous  coal. 
Their  fracture  generally  is  irregular,  with  a  tendency  to  split  along 
bedding  planes.  Some  of  the  coals  have  two  well-developed  planes 
of  fracture  at  right  angles,  but  fine  prismatic  cleavage  is  notably 
absent. 
The  composition  of  several  samples  of  coal  from  the  Colob  field  is 
shown  in  the  following  table.  The  samples  were  taken  from  the 
working  faces  of  the  mines  and  prospects  and  represent  as  fresh  coal
