Field Office Spotlight

ALERT: NOTICE OF CLOSURE for JQS Road, northwest of Rifle, Colorado. 

The Colorado River Valley Field Office is implementing an emergency temporary closure along JQS Road (Road 242), just northwest of Rifle, Colo. This emergency closure is to ensure public safety due to critical road maintenance and will remain in effect until the road work is complete, and this order is rescinded. 

BLM Road Closure Order #COG02000-23-02 prohibits all unauthorized entry pursuant to 43 CFR 8364.1.

We thank the public for their patience while construction crews diligently work to limit closure impacts. BLM expects to have the road open by the end of the weekend, depending on weather and conditions. There is an alternate access to the Roan Plateau from Highway 13 and Piceance Creek Road. 

The Colorado River Valley Field Office has added chronolog stations on the Sutey Ranch, just outside of Carbondale. Visitors can help the BLM monitor the restoration efforts by stopping at one, or all of the chornolog stations and take a quick photograph with your mobile device. Find more information at

Current restoration efforts include using goats for target grazing grazing and seeding to restore native vegetation and provide better habitat for wildlife. Visitors will be helping the BLM monitor the changes over time

Grand Hogback Trails Update

Parking Lot Construction at Grand Hogback Trails (including Rifle Arch Trail) will begin on Monday March 29, 2021 through Friday April 2, 2021. As a reminder, the trail system is closed to mechanized use Dec. 1 - April 15, due to wintering wildlife.

A new parking area will be constructed at the Grand Hogback Trails about 6 miles north of Rifle off of CO State Hwy 13. The construction will impact parking for the Rifle Arch trail. Limited parking will be available. It is advised to seek an alternate trail destination during this time.

The Grand Hogback Trails have been a collaborative effort involving the BLM, City of Rifle, Rifle Area Mountain Bike Organization, Roaring Fork Mountain Bike Association and Garfield County. Garfield County Road and Bridge will complete the parking area construction with funding from the City of Rifle. Over 6 miles of the planned 18 mile single-track trail have been constructed. The trails are built to be ‘bike optimized’ but also allow hiking and trail running. Class 1 e-bikes are allowed on the Grand Hogback trails. 🚴

Mid-Continent Quarry Information

The Colorado River Valley Field Office anticipates initiating the public comment period for the proposed Mid-Continent Quarry expansion in fall 2021, once additional baseline information is gathered. More information about the status of the proposal is here (01.06.2021). Due to the high public interest in the proposal, we have posted additional information below.

The BLM is also conducting an environmental assessment on Rocky Mountain Resource's proposal to drill five water monitoring wells as part of the Baseline Hydrologic Study. More information about that document will be added to this page when it becomes available.
