West Mojave Route Network Project (WMRNP)

Comment Period CLOSED (June 14, 2018)

Federal Register doc 2018-05272

BLM prepared a Draft Land Use Plan Amendment (LUPA) and Draft Supplemental Environmental Impact Statement (DSEIS) for the West Mojave Route Network Project (WMRNP) within the West Mojave (WEMO) Planning Area of the California Desert Conservation Area (CDCA). A 90-day comment period was opened on March 16th. The WMRNP is a significant component of the DRECP implementation. Read why the WMRNP is important for Rockhounds


Maps used to finalize motorized routes in California's deserts found to be severely flawed.
Stakeholders formally ask BLM for 90-day extension.
Read the entire article »

Several stakeholder groups surveyed selected areas within the WEMO boundaries to compare against BLM's maps provided for public comment on the WMRNP. The maps are so flawed that thirty-nine individuals and organizations, including eight rockhounds and one paleontological society, signed onto a letter asking the BLM to extend the comment period an additional 90 days, to September 12th. More time is needed for the public to grapple with the 16,000 miles of routes composed of 300,000 individual route segments (each and every one of which is clickable for comment). There are numerous redundant (overlapping) route segments with unique WEMO ID numbers, which should be consolidated into one set of segments. In addition, there are few labels and there is no separate Rockhound layer to enable hobby collectors to see what routes are relevant to their interest, specficially.

A May 30, 2018 letter prepared by Sheara Cohen et al. asking for an extension of the comment period was rejected by California BLM Director Jerome Perez on June 13th.

Many rockhounds submitted comments before the June 14th deadline, including rockhound advocates who submitted a letter (with attachments) that covered three topics all related to the WMRNP and the comment period process itself, in addition to route specific comments:

  1.    The letter memorializes the authors' communications w/ BLM and problems rockhounds and other stakeholders identified using the maps.
  2. a. The letter requests fixes to bad/questionable data or data discrepancies, better labeling.
  3. b. The letter requests an extension to the comment period after BLM fixes the bad data and/or difficult-to-use maps.
  4.    The letter resubmits past comments from WEMO-related and other geographically and subject related projects such as DRECP on gem-mineral collecting areas and route data. It was the impression of many rockhounds that the DRECP comments would be incorporated into the WEMO maps.

It would have been preferable to divide the contents into three separate letters, but given the time available, it was a single submittal. The authors thought it was likely that they were re-submitting information submitted by others previously and already in the WEMO database, but trying to sort out thousands of comments on thousands of miles of routes was beyond their best efforts, so erring on the side of caution lest anything was left out of the maps that should have been included, past submittals to WEMO and other BLM projects were re-submitted for the current DRAFT WMRNP.



Which twin has the Toni? BLM has made available two versions of maps for public comment on the West Mojave Route Network Project (WMRNP) – georeferenced PDF maps and an online interactive GIS map. Among the numerous problems with both versions is that the two sets of maps do not match. In a screenshot of the online map shown above, the highlighted (pink) route in the Cady Mountains is shown as a motorized route (lime green), but in the same view of the PDF map, the highlighted route is a translinear disturbance (brown).
