We present Spitzer infrared (IR) observations of the starless core L429. The IR images of this core show an absorption feature, caused by the dense core material, at wavelengths ≤ 70 μm. The core has a steep density profile, and reaches AV > 35 mag near the center. We show that L429 is either collapsing or in a near-collapse state.
