We introduce a stronger version of an $\omega _1$-guessing model, which we call an indestructibly $\omega _1$-guessing model. The principle $\mathsf {IGMP}$ states that there are stationarily many indestructibly $\omega _1$-guessing models. This principle, which follows from $\mathsf {PFA}$, captures many of the consequences of $\mathsf {PFA}$, including the Suslin hypothesis and the singular cardinal hypothesis. We prove that $\mathsf {IGMP}$ is consistent with the continuum being arbitrarily large.
