171.4750 is generally an Air/Ground (64) channel
National Incident Radio Support Cache - The RadioReference Wiki

Warren Peak is in Beaverhead-Deer Lodge NF

The USFS has been moving around the inputs for many of the Repeater pairs to bring them into compliance with the standard of

162-174 MHz
NTIA Manual Chapter 4 Section 4.3.7

• Government land mobile channels are normally on 12.5 kHz steps (162.05, 162.0625, 162.075 ...) in NFM, P25, or other digital voice modes.
• No standard offset.
• There are other unpaired single frequencies in other parts of the band that are not specified in the manual.
• Use of the band 162-174 MHz by the military agencies is limited to non-tactical or intra-base radio operations.
