Over the years, the Lucases created at least 15 different quarries within Garden Park. This map is adapted from a drawing found in Edward Drinker Cope's field notebook, drawn when he visited the quarries in 1879.
Click around on the map for more information about individual areas.
The following is an explanation of the roman numerals on the map, taken from Cope's description of the map in his notebook:
Localities of Saurians in the Jurassic of Canyon City S side of Saurian Hill # Lot; 200 yds from [location] of C. supremus [The "C. S." in C. S. 1 and C. S. 2 on the map refers to Camarasaurus supremus]; were found the cervical [vertebra] of Morosaurus laticollis and jaw of Hyps torhedrodon in radius of 20 feet Centrum of Amphicoelias altus
IV Immense distal end of femur near 1st broken smaller femur
V Another Camarasaurus not yet taken out
VII Dorsals of Amphicoelias w. caudals; a broken sacrum, a pubis broken & a good dorsal of Camarasaurus, & a cervical of the same
VIII 1/4 mile N. on same horizon is second Camarasaurus; this much like the type [specimen]; the skeleton is nearly complete, lacking limbs
On the same horizon round a ridge we have say 160 acres on the N,W. Side are three localities of large bones IX, X & XI not very good
XII is the Amphicoelias altus this runs into the bank head first & the anterior part of the head can probably be obtained
XIII a few bones not very good
XIV Amph. latus femur from near C. S. [Camarasaurus supremus] ter's in Oberlin [This is where the map says "A. l. Ob." Oramel Lucas appears to have taken an Amphicoelias latus femur back to school with him.] my femur came from oil tract, 1 or 2 miles from above locality from a bed of sandstone near the same horizon.
The horizon of these bones is nearly identical & is 500 feet above the red beds in bluish & lead colored marls or white sandstone below a bed of sandstone about 50 feet.
XV Humerus in sections, with a large piece of centrum of caudal [vertebrae], upper end of long bone of oval section in short drain from oil tract a mile below the A. latus [locality]."
