Meaden Pass doesn't get plowed til July 1. So it can still be snow covered in spots prior to July 1. The descent on the eastern side can be loose & rocky making it a little more technical than most descents on the ride.

While most of the Great Divide Mountain Bike Trail is bikeable with touring or gravel bikes, rare sections like these with big chunky boulders and loose rocks on steep slope provide some fun and justification for those who carried their full suspension all along the distance 😉 Including Meaden Pass, the roads are unpaved gravel, rough in places, and often covered in lingering snow into late spring or early summer.

Apart from some sandy sections, and a couple rough gravel areas on the descent, this is a pleasant and rewarding summit crossing.
