Many is the time sightings fell off and I'd stop and lean against a popple , then start a slow dissecting from it's base out to depending on density of trees ;fifteen yards or so.For early season Morels unless you know how to spot them, slow down . If you're walking then you're moving too fast to spot them. Stop. Scan. Repeat. Get down low. Then they will magically appear.
I like aspen stands.
When they were up , multiples would be spotted again. But I'd keep looking for more.
Having to relocate them ,but knowing they were there helped slow my progress.
No sense blowing past or stepping on any.
