A field journal, not a travel blog.

In the dry season of 2014, an expedition biologist and a river captain met at a field station on the Curaray River and argued, productively, about whether anything published in the travel press could be trusted by someone planning a serious expedition. They had spent the previous seven years crossing the Amazon basin on foot and by canoe — from the Putumayo to the Teles Pires, from the Essequibo to the Juruá — cataloguing canopy communities, outfitter practices, and the small, avoidable failures that turned a research trip into a rescue.

The first issue of Jungle Life was a forty-eight-page monograph bound with a treasury tag and mailed to nineteen colleagues. It carried no advertising, no affiliate links, and no photographs of the founders. What it carried were route notes, water-source timings, jaguar-track density per kilometre, and the names of the outfitters who had — and had not — met a hard set of field-readiness standards.

Ten years later, the publication is read by 38,400 expedition planners a week, has tested 312 outfitters across 23 countries, and is cited as a primary media source in three peer-reviewed papers. It is still edited from the same two field offices, still carries no banner advertising, and still answers, in the same voice, the only question a working expedition planner actually needs answered: is this place, this outfitter, this route, ready?
