With luck
About 10% of wildlife watchers report a Northern Alligator Lizard sighting in Olympic National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February–March and May–September
In those months about 10% of wildlife watchers report a Northern Alligator Lizard in Olympic National Park on a given day, against under 5% in April and October–January, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Northern Alligator Lizard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 parks where we can rate Northern Alligator Lizard sightings, Olympic National Park ranks 5th at about 10%. The best odds are in Sequoia and Kings Canyon National Parks (United States, about 40%), Redwood National Park (United States, about 30%) and Yosemite National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Northern Alligator Lizard is recorded against all the reptiles logged in Olympic National Park (19 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
