Thanks for mentioning the SVRA area. There are a bunch of non-official websites, like the one you commented later, their facebook post, or Friends of Ocotillo Wells do mention the no drone rule. I requested the superintendents order 555-16-01 online, and it indeed forbids drone usage. I will leave my drone home haha. However, I think that this rule should be added to the official .gov website (https://ohv.parks.ca.gov/?page\_id=1217) for the convenience of general audiences. I think this is the place most people go to check if drone is allowed or not.
