Experience & practicality
Two transparent read-time scores. Unknown facts never count for or against a place, and a score is never used as filter evidence.
Experience
Published recreation and setting.
4.7/ 10
Documented depth: 7.5 of 16 evidence weight, from 4 published facts. A low number means little is published, not that the place is poor.
Why
- Hiking
- Climbing
- Water nearby
- Wildlife watching
Practicality
Published logistics: access, cost, facilities.
8.1/ 10
81% of the 19 published facts are positive, scaled by how much is documented (100% of the 16-weight target). High data coverage · 8 still unpublished. A thin record reads low because little is published, not because the place is poor.
Why
- Camping is published as allowed
- 2WD passable
- Paved or gravel access road
- Restroom
- Drinking water
- Cost is published
- RV friendly
- Big rig friendly
- Maximum vehicle length published
- Pets allowed
- Trailer friendly
- Trash service
- Van friendly
- Picnic table
Published as not available
- No reservation required
- Dump station
- $25 or less per night
- Shower
- Laundry
Fully supported: both dimensions earned a score from 23 published facts.
Methodology nmr-score-3.0.0. Park-level activities feed Experience only; campsite facts feed Practicality only. Experience measures how much recreation and setting evidence is published; Practicality is the published positive share scaled by how much of the logistics catalogue has been documented, so a handful of positives can no longer read 10/10. Unknown is never treated as a no. Neither dimension is used to filter search results, and “Best” ordering ranks fully supported records above partially supported ones.
