After some early manual publishing I settled on the workflow I've used Fall 2020.
See Cross Check Lists for coordinated updates.
See Creeks Named in Pages ⇐ c-d ⇐ c-i-h-c
See Places Revisited on subsequent dates ⇐ c-d
See Navigate to Places Nearby eight ways ⇐ p-i-h-b
See Places Detailed grid of trails ⇒ markers.json 
See Chronological Wandering day by day ⇒ images.json
See Places in a Region for small maps ⇐ markers.json.
See Fall 2021 for upload automation ⇐ images.json
See Places to Consider done ⇐ markers.json ⇐ p-t-c
See Places Rendered by Season maybe by reach?
See Edit History from Journals.
