Updated at 5:455 p.m. ET: With the ground clear of winter's snow, crews on Saturday renewed the search for missing toddler Ayla Reynolds in the woods and fields of Waterville, Maine, but failed to turn up any new clues.
The girl vanished from her father's home in Waterville in December. Ayla was 20 months old at the time.
Police are treating her disappearance as a crime, but no one has been charged.
Maine Department of Public Safety spokesman Steve McCausland said the estimated 100 searchers included volunteers, firefighters and game wardens.

They were being aided by six tracking dogs, he added.
Seven-weeks after an infant went missing while in her father's care, police in Maine have resumed their underwater search for Baby Ayla. NBC's Michelle Franzen reports.
Searchers targeted places that were not thoroughly searched over the winter when the ground was covered with snow.
"The weather conditions were ideal, and the snow's gone, so that's why the ground search was resumed today," McCausland said.
McCausland also asked people in greater Kennebec County "to keep an eye on their own property for any signs that could be related to the case, now that the snow has melted."
Ayla was living with her father, Justin DiPietro, when she disappeared. She was reported missing on Dec. 17 when her father said he found her bed empty. DiPietro has said he has no idea what happened to his daughter or who is responsible.
TODAY legal correspondent Savannah Guthrie talks about the developments in the case of missing Maine toddler Ayla Reynolds and why police waited several weeks until revealing discovery of blood.
Police have received 988 tips, McCausland said.
Detectives were continuing to conduct interviews and the crime lab is providing new evidence almost daily, he said.
