State Site#: 5LK50.5-9 and 5LK50.23-36
Temporary #: N/A
36. Eligibility Recommendation (Cont'd):
Statement of Sign ificanee/N.R.H.P. Justification:
5LK50.32 - Railroad spur 5LK50.32 is recommended as a contributing element (criterion a) of the Denver &
Rio Grande Railroad system, a National Register-eligible site. The segment retains excellent visual integrity
and is readily identifiable as a railroad grade except where covered by mine waste rock. The grade appears to
have been built specifically to serve the tipple at the Ibex No. 3 Mine. The tipple is still standing and the grade
is an integral component of the feature. Because of the grade's visual integrity and its association with the Ibex
Mine complex,it is also considered to be a contributing element of the Leadville Mining District(5LK&%).
5LK50.33 - Railroad spur 5LK50.33 is not recommended as a contributing element of the Denver & Rio
Grande Railroad system, a National Register-eligible site. The segment consists of only two small remnants of
the grade and has been mostly covered with mine waste rock. Because of the grade's poor physical integrity, it
is not recommended as a contributing element of the Leadvilde Mining District(5LK856).
5LK50.34- Railroad spur 5LIC50.34 is recommended as a contributing element(criterion a)of the Denver &Rio
Grande Railroad system, a National Register-eligible site. Although the spur is not as visually impressive as
others in the area, it is the only piece of grade with a distinct side track in association. In addition, the grade
has good association with the machinery area of the Ibex No. 2 Mine. Because of the grade's physical
characteristics and association with the Ibex No. 2 Mine, it is also considered to be a contributing element of the
Leadville Mining District(5LK856).
5LK50.35 - Railroad spur 5LK50.35 is recommended as a contributing element (criterion a) of the Denver&
Rio Grande Railroad system, a National Register-eligible site. The segment retains excellent visual integrity
and is readily identifiable as a railroad grade. The grade appears to have been built specifically to serve the
Garbutt Mine. Because of the grade's visual integrity, it is also considered to be a contributing element of the
Leadville Mining District(5LK856).
5LK50.36 - Railroad spur 5LI(50.36 is not recommended as a contributing element of the Denver & Rio
Grande Railroad system, a National Register-eligible site. The segment has poor physical and visual integrity
and is not readily identifiable as a railroad grade. Because of the grade's poor integrity and its association with
the Ibex Mine complex, it is not recommended as a contributing element of the Leadville Mining District
(5LIC85Q.
43. Management Recommendations (Cont'd):
5LK50.5 - Segment 5LK50.5 should be avoided by all project impacts, including heavy vehicle use and
upgrading. If avoidance is not possible, the areas that will be impacted should be photographically documented
prior to disturbance.
5LK50.6 - No further historical or archaeological work should be required for segment 5LIC50.6. Recordation
has sufficiently documented the segment.
5LK50.7 - No further historical or archaeological work should be required for segment 5LK50.7. Recordation
has sufficiently documented the segment.
5LK50.8 - Segment 5LIC50.8 should be avoided by all project impacts, including heavy vehicle use and
upgrading. If avoidance is not possible, the areas that will be impacted should be photographically documented
prior to disturbance.
